The coating is deposited on by physical vapor deposition (PVD) method. The working conditions of the blade were simulated and surface temperature and pressure values as well as flow velocity and flow direction were obtained. This data was used in the finite element wear model developed here in order to predict the wear of the blade. The wear mechanisms considered are erosive wear due to particle impingement and fluid jet, and fatigue wear due to repeated impingement of particles and fluid jet. Results show that the life of the TiN-coated blade is approximately 1.76 times longer than the life of the uncoated one. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=physical%20vapour%20deposition" title="physical vapour deposition">physical vapour deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=steam%20turbine%20blade" title=" steam turbine blade"> steam turbine blade</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium-based%20coating" title=" titanium-based coating"> titanium-based coating</a>, <a href="https://publications.waset.org/abstracts/search?q=wear%20prediction" title=" wear prediction"> wear prediction</a> </p> <a href="https://publications.waset.org/abstracts/8420/computational-study-and-wear-prediction-of-steam-turbine-blade-with-titanium-nitride-coating-deposited-by-physical-vapor-deposition-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8420.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">373</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7005</span> Effect of the Deposition Time of Hydrogenated Nanocrystalline Si Grown on Porous Alumina Film on Glass Substrate by Plasma Processing Chemical Vapor Deposition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20Laatar">F.

Influence of the deposition time on the physical properties of nc-Si: H grown on PAF was investigated through an extensive correlation between micro-structural and optical properties of these films. In this paper, we present an extensive study of the morphological, structural and optical properties of these films by Atomic Force Microscopy (AFM), X-Ray Diffraction (XRD) techniques and a UV-Vis-NIR spectrometer. It was found that the changes in DT can modify the films thickness, the surface roughness and eventually improve the optical properties of the composite. Optical properties (optical thicknesses, refractive indexes (n), absorption coefficients (α), extinction coefficients (k), and the values of the optical transitions EG) of this kind of samples were obtained using the data of the transmittance T and reflectance R spectra’s recorded by the UV–Vis–NIR spectrometer. We used Cauchy and Wemple–DiDomenico models for the analysis of the dispersion of the refractive index and the determination of the optical properties of these films. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydragenated%20nanocrystalline%20silicon" title="hydragenated nanocrystalline silicon">hydragenated nanocrystalline silicon</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma%20processing%20chemical%20vapor%20deposition" title=" plasma processing chemical vapor deposition"> plasma processing chemical vapor deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=X-ray%20diffraction" title=" X-ray diffraction"> X-ray diffraction</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20properties" title=" optical properties"> optical properties</a> </p> <a href="https://publications.waset.org/abstracts/6992/effect-of-the-deposition-time-of-hydrogenated-nanocrystalline-si-grown-on-porous-alumina-film-on-glass-substrate-by-plasma-processing-chemical-vapor-deposition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6992.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">377</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7004</span> Metal-Organic Chemical Vapor Deposition (MOCVD) Process Investigation for Co Thin Film as a TSV Alternative Seed Layer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sajjad%20Esmaeili">Sajjad Esmaeili</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Krause"> Robert Krause</a>, <a href="https://publications.waset.org/abstracts/search?q=Lukas%20Gerlich"> Lukas Gerlich</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Mohammadian%20Kia"> Alireza Mohammadian Kia</a>, <a href="https://publications.waset.org/abstracts/search?q=Benjamin%20Uhlig"> Benjamin Uhlig</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This investigation aims to develop the feasible and qualitative process parameters for the thin films fabrication into ultra-large through-silicon-vias (TSVs) as vertical interconnections. The focus of the study is on TSV metallization and its challenges employing new materials for the purpose of rapid signal propagation in the microsystems technology. Cobalt metal-organic chemical vapor deposition (Co-MOCVD) process enables manufacturing an adhesive and excellent conformal ultra-thin film all the way through TSVs in comparison with the conventional non-conformal physical vapor deposition (PVD) process of copper (Cu) seed layer. Therefore, this process provides a Cu seed-free layer which is capable of direct Cu electrochemical deposition (Cu-ECD) on top of it. The main challenge of this metallization module is to achieve the proper alternative seed layer with less roughness, sheet resistance and granular organic contamination (e.g. carbon) which intensify the Co corrosion under the influence of Cu electrolyte. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cobalt%20MOCVD" title="Cobalt MOCVD">Cobalt MOCVD</a>, <a href="https://publications.waset.org/abstracts/search?q=direct%20Cu%20electrochemical%20deposition%20%28ECD%29" title=" direct Cu electrochemical deposition (ECD)"> direct Cu electrochemical deposition (ECD)</a>, <a href="https://publications.waset.org/abstracts/search?q=metallization%20technology" title=" metallization technology"> metallization technology</a>, <a href="https://publications.waset.org/abstracts/search?q=through-silicon-via%20%28TSV%29" title=" through-silicon-via (TSV)"> through-silicon-via (TSV)</a> </p> <a href="https://publications.waset.org/abstracts/96811/metal-organic-chemical-vapor-deposition-mocvd-process-investigation-for-co-thin-film-as-a-tsv-alternative-seed-layer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96811.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">158</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7003</span> Generation of Charged Nanoparticles in the Gas Phase and their Contribution to Deposition of GaN Films and Nanostructures during Atmospheric Pressure Chemical Vapor Deposition </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jin-Woo%20Park">Jin-Woo Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung-Soo%20Lee"> Sung-Soo Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Nong-Moon%20Hwang"> Nong-Moon Hwang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The generation of charged nanoparticles in the gas phase during the Chemical Vapor Deposition (CVD) process has been frequently reported with their subsequent deposition into films and nanostructures in many systems such as carbon, silicon and zinc oxide. The microstructure evolution of films and nanostructures is closely related with the size distribution of charged nanoparticles. To confirm the generation of charged nanoparticles during GaN, the generation of GaN charged nanoparticles was examined in an atmospheric pressure CVD process using a Differential Mobility Analyser (DMA) combined with a Faraday Cup Electrometer (FCE). It was confirmed that GaN charged nanoparticles were generated under the condition where GaN nanostructures were synthesized on the bare and Au-coated Si substrates. In addition, the deposition behaviour depends strongly on the charge transfer rate of metal substrates. On the metal substrates of a lower CTR such as Mo, the deposition rate of GaN was much lower than on those of a higher CTR such as Fe. GaN nanowires tend to grow on the substrates of a lower CTR whereas GaN thin films tend to be deposited on the substrates of a higher CTR. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemical%20vapour%20deposition" title="chemical vapour deposition">chemical vapour deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=charged%20cluster%20model" title=" charged cluster model"> charged cluster model</a>, <a href="https://publications.waset.org/abstracts/search?q=generation%20of%20charged%20nanoparticles" title=" generation of charged nanoparticles"> generation of charged nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=deposition%20behaviour" title=" deposition behaviour"> deposition behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=nanostructures" title=" nanostructures"> nanostructures</a>, <a href="https://publications.waset.org/abstracts/search?q=gan" title=" gan"> gan</a>, <a href="https://publications.waset.org/abstracts/search?q=charged%20transfer%20rate" title=" charged transfer rate"> charged transfer rate</a> </p> <a href="https://publications.waset.org/abstracts/2530/generation-of-charged-nanoparticles-in-the-gas-phase-and-their-contribution-to-deposition-of-gan-films-and-nanostructures-during-atmospheric-pressure-chemical-vapor-deposition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2530.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">439</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7002</span> Corrosion Behavior of Different Electroplated Systems Coated With Physical Vapor Deposition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Santos">Jorge Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20V.%20Gir%C3%A3o"> Ana V.

These hexavalent chromium compounds represent a risk to living beings and the environment, and, for this reason, there is a great need to investigate alternatives. Physical Vapor Deposition (PVD) is an environmentally friendly process that allows the deposition of wear and corrosion resistant thin films with excellent optical properties. However, PVD thin films are porous and if deposited onto low corrosion resistant substrates, lead to a degradation risk. The corrosion behavior of chromium-free electroplated coating systems finished with magnetron sputtered PVD thin films was investigated in this work. The electroplated systems consisted of distinct nickel layers deposited on top of a copper interlayer on acrylonitrile butadiene styrene (ABS) plates. Electrochemical and corrosion evaluation was conducted by electrochemical impedance spectroscopy and polarization curves on the different electroplated coating systems, with and without PVD thin film on top. The results show that the corrosion resistance is lower for the electroplated coating systems finished with PVD thin film for extended exposure periods when compared to those without the PVD overlay. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PVD" title="PVD">PVD</a>, <a href="https://publications.waset.org/abstracts/search?q=electroplating" title=" electroplating"> electroplating</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion" title=" corrosion"> corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20film" title=" thin film"> thin film</a> </p> <a href="https://publications.waset.org/abstracts/153146/corrosion-behavior-of-different-electroplated-systems-coated-with-physical-vapor-deposition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153146.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">147</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7001</span> Electrical Properties of CVD-Graphene on SiC</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bilal%20Jabakhanji">Bilal Jabakhanji</a>, <a href="https://publications.waset.org/abstracts/search?q=Dimitris%20Kazazis"> Dimitris Kazazis</a>, <a href="https://publications.waset.org/abstracts/search?q=Adrien%20Michon"> Adrien Michon</a>, <a href="https://publications.waset.org/abstracts/search?q=Christophe%20Consejo"> Christophe Consejo</a>, <a href="https://publications.waset.org/abstracts/search?q=Wilfried%20Desrat"> Wilfried Desrat</a>, <a href="https://publications.waset.org/abstracts/search?q=Benoit%20Jouault"> Benoit Jouault</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we investigate the electrical properties of graphene grown by Chemical Vapor Deposition (CVD) on the Si face of SiC substrates.

We performed a systematic optimization of CVD parameters such as deposition temperature, working pressure and annealing time and temperature to obtain high-quality films of CH3NH3PbI3, CH3NH3PbI3-xBrx and CH3NH3PbI3-xClx perovskite. Scanning electron microscopy and X-ray Diffraction pattern showed that the perovskite films have a large grain size when compared to traditional spin coated thin films. To the best of our knowledge, there are very few reports on highly quality perovskite thin films by various doping such as Br and Cl using one step CVD and there is scope for significant improvement in device efficiency. In addition, their band-gap can be conveniently and widely tuned via doping process. This deposition process produces perovskite thin films with large grain size, long diffusion length and high surface coverage. The enhancement of the output power, CH3NH3PbI3 (MAPbI3) dye films when compared to spin coated films and enhancement in output power by doping in doped films was demonstrated in detail. The facile one-step method for deposition of perovskite thin films shows a potential candidate for photovoltaic and energy harvesting applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=perovskite%20thin%20films" title="perovskite thin films">perovskite thin films</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20vapor%20deposition" title=" chemical vapor deposition"> chemical vapor deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20harvesting" title=" energy harvesting"> energy harvesting</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaics" title=" photovoltaics"> photovoltaics</a> </p> <a href="https://publications.waset.org/abstracts/60232/fabrication-of-pure-and-doped-mapbi3-thin-films-by-one-step-chemical-vapor-deposition-method-for-energy-harvesting-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60232.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">308</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6999</span> Electrochemical Performance of Carbon Nanotube Based Supercapacitor </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jafar%20Khan%20Kasi">Jafar Khan Kasi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ajab%20Khan%20Kasi"> Ajab Khan Kasi</a>, <a href="https://publications.waset.org/abstracts/search?q=Muzamil%20Bokhari"> Muzamil Bokhari </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Carbon nanotube is one of the most attractive materials for the potential applications of nanotechnology due to its excellent mechanical, thermal, electrical and optical properties.

High graphitic multiwall carbon nanotube was found at 750 C analyzing by Raman spectroscopy. We observed the electrochemical performance of supercapacitor by cyclic voltammetry. The electrodes of supercapacitor fabricated from MWCNTs exhibit considerably small equivalent series resistance (ESR), and a high specific power density. Electrophoretic deposition is an easy method in fabricating MWCNT electrodes for high performance supercapacitor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanotube" title="carbon nanotube">carbon nanotube</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20vapor%20deposition" title=" chemical vapor deposition"> chemical vapor deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=catalyst" title=" catalyst"> catalyst</a>, <a href="https://publications.waset.org/abstracts/search?q=charge" title=" charge"> charge</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclic%20voltammetry" title=" cyclic voltammetry "> cyclic voltammetry </a> </p> <a href="https://publications.waset.org/abstracts/20355/electrochemical-performance-of-carbon-nanotube-based-supercapacitor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20355.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">563</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6998</span> Impact of Prolonged Sodium Hypochlorite Cleaning on Silicon Carbide Ultrafiltration Membranes Prepared via Low-Pressure Chemical Vapor Deposition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asif%20Jan">Asif Jan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sodium hypochlorite (NaClO) is a common cleaning agent for ultrafiltration (UF) membranes. While its detrimental effects on polymeric membranes are well-documented, its impact on ceramic membranes remains less explored. This study investigates the chemical stability of silicon carbide (SiC) UF membranes prepared using low-pressure chemical vapor deposition (LP-CVD) during prolonged NaClO exposure. SiC UF membranes were fabricated via LP-CVD at two different temperature and pressure conditions. LP-CVD offers the advantage of SiC membrane fabrication at significantly lower temperatures (700-900°C) compared to conventional methods. The membranes were subjected to 200 hours of NaClO aging to assess their resilience. Before and after aging, we evaluated the properties and performance of the SiC UF membranes to identify optimal LP-CVD conditions. Our findings show that SiC UF membranes produced at 860°C via LP-CVD exhibit exceptional resistance to NaClO aging, whereas those prepared at 750°C experience significant deterioration. This highlights the crucial role of precise LP-CVD parameters in ensuring the robustness and long-term performance of SiC membranes in harsh chemical cleaning environments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ceramic%20membranes" title="ceramic membranes">ceramic membranes</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrafiltration%20membranes" title=" ultrafiltration membranes"> ultrafiltration membranes</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater%20treatment" title=" wastewater treatment"> wastewater treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20vapor%20deposition" title=" chemical vapor deposition"> chemical vapor deposition</a> </p> <a href="https://publications.waset.org/abstracts/174165/impact-of-prolonged-sodium-hypochlorite-cleaning-on-silicon-carbide-ultrafiltration-membranes-prepared-via-low-pressure-chemical-vapor-deposition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174165.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">91</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6997</span> Growth Nanostructured CdO Thin Film via Solid-Vapor Deposition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20S.%20Obaid">A.

During chip manufacturing, structures are filled for example by metal organic chemical vapor deposition (MOCVD). Since this process reaches its limits in case of very high aspect ratios, the use of alternatives such as the atomic layer deposition (ALD) is possible, requiring the extension of existing coating systems. However, it is an unsolved question to what extent MOCVD can achieve results similar as an ALD process. In this context, this work addresses the characterization of a metal organic vapor deposition of titanium nitride. Based on the current state of the art, the film properties coating thickness, sheet resistance, resistivity, stress and chemical composition are considered. The used setting parameters are temperature, plasma gas ratio, plasma power, plasma treatment time, deposition time, deposition pressure, number of cycles and TDMAT flow. The derived process instructions for unstructured wafers and inside a structure with high aspect ratio include lowering the process temperature and increasing the number of cycles, the deposition and the plasma treatment time as well as the plasma gas ratio of hydrogen to nitrogen (H<sub>2</sub>:N<sub>2</sub>). In contrast to the current process configuration, the deposited titanium nitride (TiN) layer is more uniform inside the entire test structure. Consequently, this paper provides approaches to employ the MOCVD for structures with increasing aspect ratios. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ALD" title="ALD">ALD</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20aspect%20ratio" title=" high aspect ratio"> high aspect ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=PE-MOCVD" title=" PE-MOCVD"> PE-MOCVD</a>, <a href="https://publications.waset.org/abstracts/search?q=TiN" title=" TiN"> TiN</a> </p> <a href="https://publications.waset.org/abstracts/50360/approximation-of-pe-mocvd-to-ald-for-tin-concerning-resistivity-and-chemical-composition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50360.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">300</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6994</span> Antireflection Performance of Graphene Directly Deposited on Silicon Substrate by the Atmospheric Pressure Chemical Vapor Deposition Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samira%20Naghdi">Samira Naghdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyong%20Yop%20Rhee"> Kyong Yop Rhee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Transfer-free synthesis of graphene on dielectric substrates is highly desirable but remains challenging. Here, by using a thin sacrificial platinum layer as a catalyst, graphene was deposited on a silicon substrate through a simple and transfer-free synthesis method. During graphene growth, the platinum layer evaporated, resulting in direct deposition of graphene on the silicon substrate. In this work, different growth conditions of graphene were optimized. Raman spectra of the produced graphene indicated that the obtained graphene was bilayer. The sheet resistance obtained from four-point probe measurements demonstrated that the deposited graphene had high conductivity. Reflectance spectroscopy of graphene-coated silicon showed a decrease in reflectance across the wavelength range of 200-800 nm, indicating that the graphene coating on the silicon surface had antireflection capabilities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antireflection%20coating" title="antireflection coating">antireflection coating</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20vapor%20deposition" title=" chemical vapor deposition"> chemical vapor deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene" title=" graphene"> graphene</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20sheet%20resistance" title=" the sheet resistance"> the sheet resistance</a> </p> <a href="https://publications.waset.org/abstracts/92381/antireflection-performance-of-graphene-directly-deposited-on-silicon-substrate-by-the-atmospheric-pressure-chemical-vapor-deposition-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92381.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">180</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6993</span> Tin and Tin-Copper Composite Nanorod Anodes for Rechargeable Lithium Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20D.%20Polat">B.

These columns will be oriented toward the vapor source because of the self-shadowing effect, and they are homogenously distributed on the substrate surface because of the limited surface diffusion ability of ad-atoms when there is no additional substrate heating. In this work, the oblique angle electron beam evaporation technique is used to fabricate thin films containing inclined nanorods. The results demonstrate that depending on the thin film composition, the morphology of the nanorods changed as well. The galvanostatic analysis of these thin film anodes reveals that a composite CuSn nanorods having approximately 900mAhg-1 of initial discharge capacity, performs higher electrochemical performance compared to pure Sn nanorods containing anode material. The long cycle life and the advanced electrochemical properties of the nano-structured composite electrode might be attributed to its improved mechanical tolerance and enhanced electrical conductivity depending on the Cu presence in the nanorods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cu-Sn%20thin%20film" title="Cu-Sn thin film">Cu-Sn thin film</a>, <a href="https://publications.waset.org/abstracts/search?q=oblique%20angle%20deposition" title=" oblique angle deposition"> oblique angle deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium%20ion%20batteries" title=" lithium ion batteries"> lithium ion batteries</a>, <a href="https://publications.waset.org/abstracts/search?q=anode" title=" anode"> anode</a> </p> <a href="https://publications.waset.org/abstracts/2210/tin-and-tin-copper-composite-nanorod-anodes-for-rechargeable-lithium-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2210.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">347</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6992</span> In2S3 Buffer Layer Properties for Thin Film Solar Cells Based on CIGS Absorber </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Bouloufa">A.

In this paper, a thermal deposition technique is utilized as a method to fabricate antenna structures on substrates. Thin-film deposition is achieved by evaporating a source material (metals in our case) in a vacuum which allows vapor particles to travel directly to the target substrate which is encased with a mask that outlines the desired structure. The material then condenses back to solid state. This method is used in comparison to screen printing, chemical etching, and ink jet printing to indicate advantages and disadvantages to the method. The antenna created undergoes various testing of frequency ranges, conductivity, and a series of flexing to indicate the effectiveness of the thermal deposition technique. A single band antenna that is operated at 2.45 GHz intended for wearable and flexible applications was successfully fabricated through this method and tested. It is concluded that thermal deposition presents a feasible technique of producing such antennas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermal%20deposition" title="thermal deposition">thermal deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=wearable%20antennas" title=" wearable antennas"> wearable antennas</a>, <a href="https://publications.waset.org/abstracts/search?q=bluetooth%20technology" title=" bluetooth technology"> bluetooth technology</a>, <a href="https://publications.waset.org/abstracts/search?q=flexible%20electronics" title=" flexible electronics"> flexible electronics</a> </p> <a href="https://publications.waset.org/abstracts/56810/fabrication-of-wearable-antennas-through-thermal-deposition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56810.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">282</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6989</span> Nano Effects of Nitrogen Ion Implantation on TiN Hard Coatings Deposited by Physical Vapour Deposition and Ion Beam Assisted Deposition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Branko%20Skoric">Branko Skoric</a>, <a href="https://publications.waset.org/abstracts/search?q=Aleksandar%20Miletic"> Aleksandar Miletic</a>, <a href="https://publications.waset.org/abstracts/search?q=Pal%20Terek"> Pal Terek</a>, <a href="https://publications.waset.org/abstracts/search?q=Lazar%20Kovacevic"> Lazar Kovacevic</a>, <a href="https://publications.waset.org/abstracts/search?q=Milan%20Kukuruzovic"> Milan Kukuruzovic </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we present the results of a study of TiN thin films which are deposited by a Physical Vapour Deposition (PVD) and Ion Beam Assisted Deposition (IBAD).

A variety of analytic techniques were used for characterization, such as scratch test, calo test, Scanning electron microscopy (SEM), Atomic Force Microscope (AFM), X-ray diffraction (XRD) and Energy Dispersive X-ray analysis (EDAX). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coating" title="coating">coating</a>, <a href="https://publications.waset.org/abstracts/search?q=super%20hard" title=" super hard"> super hard</a>, <a href="https://publications.waset.org/abstracts/search?q=ion%20implantation" title=" ion implantation"> ion implantation</a>, <a href="https://publications.waset.org/abstracts/search?q=nanohardness" title=" nanohardness"> nanohardness</a> </p> <a href="https://publications.waset.org/abstracts/42278/nano-effects-of-nitrogen-ion-implantation-on-tin-hard-coatings-deposited-by-physical-vapour-deposition-and-ion-beam-assisted-deposition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42278.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">346</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6988</span> Single-Walled Carbon Nanotube Synthesis by Chemical Vapor Deposition Using Platinum-Group Metal Catalysts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20Maruyama">T.

However, due to the Ostwald ripening of metal catalysts, the diameter distribution of the grown SWCNTs is considerably wide (>2 nm), which is not suitable for electronics applications. In addition, reduction in the growth temperature is desirable for fabricating SWCNT devices compatible with the LSI process. Herein, we performed SWCNT growth by alcohol catalytic CVD using platinum-group metal catalysts (Pt, Rh, and Pd) because these metals have high melting points, and the reduction in the Ostwald ripening of catalyst particles is expected. Our results revealed that web-like SWCNTs were obtained from Pt and Rh catalysts at growth temperature between 500 °C and 600 °C by optimizing the ethanol pressure. The SWCNT yield from Pd catalysts was considerably low. By decreasing the growth temperature, the diameter and chirality distribution of SWCNTs from Pt and Rh catalysts became small and narrow. In particular, the diameters of most SWCNTs grown using Pt catalysts were below 1 nm and their diameter distribution was considerably narrow. On the contrary, SWCNTs can grow from Rh catalysts even at 300 °C by optimizing the growth condition, which is the lowest temperature recorded for SWCNT growth. Our results demonstrated that platinum-group metals are useful for the growth of small-diameter SWCNTs and facilitate low-temperature growth. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanotube" title="carbon nanotube">carbon nanotube</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20vapor%20deposition" title=" chemical vapor deposition"> chemical vapor deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=catalyst" title=" catalyst"> catalyst</a>, <a href="https://publications.waset.org/abstracts/search?q=platinum" title=" platinum"> platinum</a>, <a href="https://publications.waset.org/abstracts/search?q=rhodium" title=" rhodium"> rhodium</a>, <a href="https://publications.waset.org/abstracts/search?q=palladium" title=" palladium"> palladium</a> </p> <a href="https://publications.waset.org/abstracts/90219/single-walled-carbon-nanotube-synthesis-by-chemical-vapor-deposition-using-platinum-group-metal-catalysts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90219.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">347</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6987</span> Controlled Growth of Charge Transfer Complex Nanowire by Physical Vapor Deposition Method Using Dielectrophoretic Force</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rabaya%20Basori">Rabaya Basori</a>, <a href="https://publications.waset.org/abstracts/search?q=Arup%20K.%20Raychaudhuri"> Arup K.

Dielectrophoresis (DEP) has been widely investigated as a scalable technique to trap and manipulate polarizable objects. This includes biological cells, nanoparticles, DNA molecules, organic or inorganic NWs and proteins using electric field gradients. In this article, we have used DEP force to localize nanowire growth by physical vapor deposition (PVD) method as well as control of NW diameter on field assisted growth of the NWs of CuTCNQ (Cu-tetracyanoquinodimethane); a metal-organic charge transfer complex material which is well known of resistive switching. We report a versatile analysis platform, based on a set of nanogap electrodes, for the controlled growth of nanowire. Non-uniform electric field and dielectrophoretic force is created in between two metal electrodes, patterned by electron beam lithography process. Suspended CuTCNQ nanowires have been grown laterally between two electrodes in the vicinity of electric field and dielectric force by applying external bias. Growth and diameter dependence of the nanowires on external bias has been investigated in the framework of these two forces by COMSOL Multiphysics simulation. This report will help successful in-situ nanodevice fabrication with constrained number of NW and diameter without any post treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanowire" title="nanowire">nanowire</a>, <a href="https://publications.waset.org/abstracts/search?q=dielectrophoretic%20force" title=" dielectrophoretic force"> dielectrophoretic force</a>, <a href="https://publications.waset.org/abstracts/search?q=confined%20growth" title=" confined growth"> confined growth</a>, <a href="https://publications.waset.org/abstracts/search?q=controlled%20diameter" title=" controlled diameter"> controlled diameter</a>, <a href="https://publications.waset.org/abstracts/search?q=comsol%20multiphysics%20simulation" title=" comsol multiphysics simulation"> comsol multiphysics simulation</a> </p> <a href="https://publications.waset.org/abstracts/70925/controlled-growth-of-charge-transfer-complex-nanowire-by-physical-vapor-deposition-method-using-dielectrophoretic-force" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70925.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">192</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6986</span> Fiber-Optic Sensors for Hydrogen Peroxide Vapor Measurement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Akbari%20Khorami">H.

H2O2 has extensive applications in industrial and medical environments. Conversely, H2O2 can be a health hazard by itself. For example, H2O2 induces cellular damage in human cells and its presence can be used to diagnose illnesses such as asthma and human breast cancer. Hence, development of reliable H2O2 sensor is of vital importance to detect and measure this species. Ferric ferrocyanide, referred to as Prussian blue (PB), was deposited on the tip of a multimode optical fiber through the single source precursor technique and served as an indicator of H2O2 in a spectroscopic manner. Sensing tests were performed in H2O2-H2O vapor mixtures with different concentrations of H2O2. The results of sensing tests show the sensor is able to detect H2O2 concentrations in the range of 50.6 ppm to 229.5 ppm. Furthermore, the sensor response to H2O2 concentrations is linear in a log-log scale with the adjacent R-square of 0.93. This sensing behavior allows us to detect and quantify the concentration of H2O2 in the vapor phase. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemical%20deposition" title="chemical deposition">chemical deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=fiber-optic%20sensor" title=" fiber-optic sensor"> fiber-optic sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20peroxide%20vapor" title=" hydrogen peroxide vapor"> hydrogen peroxide vapor</a>, <a href="https://publications.waset.org/abstracts/search?q=prussian%20blue" title=" prussian blue"> prussian blue</a> </p> <a href="https://publications.waset.org/abstracts/35449/fiber-optic-sensors-for-hydrogen-peroxide-vapor-measurement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35449.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">358</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6985</span> Chemical Vapor Deposition (CVD) of Molybdenum Disulphide (MoS2) Monolayers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Omar%20Omar">Omar Omar</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuan%20Jun"> Yuan Jun</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Jinghua"> Hong Jinghua</a>, <a href="https://publications.waset.org/abstracts/search?q=Jin%20Chuanhong"> Jin Chuanhong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work molybdenum dioxide (MoO2) and sulphur powders are used to grow MoS2 mono layers at elevated temperatures T≥800 °C.

In this approach, the Cu.ZnO nanoplate thin films were grown by using acetic acid to promote preferential growth and enhance surface active sites, where Cu nanoparticles can be formed under chemical deposition by reduction of Cu salt. Studies using photoluminescence spectroscopy indicate the enhanced photocatalytic performance is attributed to hot electron generated from SPR. The Cu metal in the composite material is functioning as a sensitizer to supply electrons to the semiconductor resulting in enhanced electron density for redox reaction. This work not only describes a way to obtain photoanodes with high photocatalytic activity but also suggests a low-cost route towards production of photocatalysts for hydrogen production. This work also supports a vital need to understand electron transfer between photoexcited semiconductor materials and metals, a requirement for tailoring the properties of semiconductor/metal composites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=photocatalysis" title="photocatalysis">photocatalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=photoelectrochemical%20cell%20%28PEC%29" title=" photoelectrochemical cell (PEC)"> photoelectrochemical cell (PEC)</a>, <a href="https://publications.waset.org/abstracts/search?q=aerosol-assisted%20chemical%20vapor%20deposition%20%28AACVD%29" title=" aerosol-assisted chemical vapor deposition (AACVD)"> aerosol-assisted chemical vapor deposition (AACVD)</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20plasmon%20resonance%20%28SPR%29" title=" surface plasmon resonance (SPR)"> surface plasmon resonance (SPR)</a> </p> <a href="https://publications.waset.org/abstracts/138288/cu-nanoparticle-embedded-zno-nanoplate-thin-films-for-highly-efficient-photocatalytic-hydrogen-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138288.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">219</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6983</span> Design of a Controlled BHJ Solar Cell Using Modified Organic Vapor Spray Deposition Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20Stephen%20Joe">F.

In order to use a graphene layer as a water desalination membrane, fabrication of crack-free suspension of graphene on a porous membrane, having hydrophobic surface, and generation of a uniform holes on a graphene are very important. In here, we showed a simple chemical vapor deposition (CVD) method to create a patterned graphene membrane on a patterned platinum film. After CVD growth process of patterned graphene layer/patterned Pt on SiO2 substrates, the patterned graphene layer can be successfully transferred onto arbitrary substrates via thermal-assisted transfer method. In this result, the transferred patterned graphene membrane has so hydrophobic surface which will certainly impact on the naturally and speed pass way for fresh water. In addition to this, we observed that overlapping of patterned graphene membranes reported previously by our group may generate different size of holes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemical%20vapor%20deposition%20%28CVD%29" title="chemical vapor deposition (CVD)">chemical vapor deposition (CVD)</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrophobic%20surface" title=" hydrophobic surface"> hydrophobic surface</a>, <a href="https://publications.waset.org/abstracts/search?q=membrane%20desalination" title=" membrane desalination"> membrane desalination</a>, <a href="https://publications.waset.org/abstracts/search?q=porous%20graphene" title=" porous graphene"> porous graphene</a> </p> <a href="https://publications.waset.org/abstracts/57970/next-generation-membrane-for-water-desalination-facile-fabrication-of-patterned-graphene-membrane" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57970.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">471</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6981</span> Characterization of Nanostructured and Conventional TiAlN and AlCrN Coated ASTM-SA213-T-11 Boiler Steel </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vikas%20Chawla">Vikas Chawla</a>, <a href="https://publications.waset.org/abstracts/search?q=Buta%20Singh%20Sidhu"> Buta Singh Sidhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Amita%20Rani"> Amita Rani</a>, <a href="https://publications.waset.org/abstracts/search?q=Amit%20Handa"> Amit Handa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main objective of the present work is microstructural and mechanical characterization of the conventional and nanostructured TiAlN and AlCrN coatings deposited on T-11 boiler steel.

The physical vapor deposition process (PAPVD) was employed for depositing nanostructured TiAlN and AlCrN coatings. The field emission scanning electron microscopy (FE-SEM) with energy dispersive X-ray analysis (EDAX) attachment, X-ray diffraction (XRD) analysis, atomic force microscopy (AFM) analysis and the X-Ray mapping analysis techniques have been used to study surface and cross-sectional morphology of the coatings. The surface roughness and micro-hardness were also measured. A good adhesion of the conventional thick TiAlN and AlCrN coatings was found.

The high C solubility of Ni made it one of the most used in CNTs synthesis. Nevertheless, Ni presents also sintering and coalescence at high temperature. These troubles can be reduced by choosing a suitable support. We propose La₂Zr₂O₇ as for this matter since the incorporation of Ni by co-precipitation and calcination at 900 °C allows a good dispersion and interaction of the active metal (in the oxidized form, NiO) with this support. The CCVD was performed using 1 g of Ni20LZO at 950 °C during 30 min in Ar:H₂ atmosphere (2.5 L/min). The precursor, benzylamine, was added by a nebulizer-sprayer. X ray diffraction study shows the phase separation of NiO and La₂Zr₂O₇ after the calcination and the reduction to Ni after the synthesis. Raman spectra show D and G bands with a ID/IG ratio of 0.75. Elemental study verifies the incorporation of 1% of N. Thermogravimetric analysis shows the oxidation process start at around 450 °C.

The use of magnetic particle decorated carbon nanotubes increases the applications in magnetic devices, magnetic memory, and magnetic oriented drug delivery. In this work, single-walled carbon nanotubes (CNTs) forest decorated with chromium were deposited at room temperature by high-density plasma chemical vapor deposition (HDPCVD) system. The CNTs forest was obtained using pure methane plasmas and chromium, as precursor material (seed) and for decorating the CNTs. Magnetron sputtering deposited the chromium on silicon wafers before the CNTs' growth. Scanning electron microscopy, atomic force microscopy, micro-Raman spectroscopy, and X-ray diffraction characterized the single-walled CNTs forest decorated with chromium. In general, the CNTs' spectra show a unique emission band, but due to the presence of the chromium, the spectra obtained in this work showed many bands that are related to the CNTs with different diameters. The CNTs obtained by the HDPCVD system are highly aligned and showed metallic features, and they can be used as photonic material, due to the unique structural and electrical properties. The results of this work proved the possibility of obtaining the controlled deposition of aligned single-walled CNTs forest films decorated with chromium by high-density plasma chemical vapor deposition system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CNTs%20forest" title="CNTs forest">CNTs forest</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20density%20plasma%20deposition" title=" high density plasma deposition"> high density plasma deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=high-aligned%20CNTs" title=" high-aligned CNTs"> high-aligned CNTs</a>, <a href="https://publications.waset.org/abstracts/search?q=nanomaterials" title=" nanomaterials"> nanomaterials</a> </p> <a href="https://publications.waset.org/abstracts/110542/characterization-of-single-walled-carbon-nano-tubes-forest-decorated-with-chromium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110542.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">117</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6978</span> Study of Fork Marks on Sapphire Wafers in Plasma Enhanced Chemical Vapor Deposition Tool</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Qiao%20Pei%20Wen">Qiao Pei Wen</a>, <a href="https://publications.waset.org/abstracts/search?q=Ng%20Seng%20Lee"> Ng Seng Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Sae%20Tae%20Veera"> Sae Tae Veera</a>, <a href="https://publications.waset.org/abstracts/search?q=Chiu%20Ah%20Fong"> Chiu Ah Fong</a>, <a href="https://publications.waset.org/abstracts/search?q=Loke%20Weng%20Onn"> Loke Weng Onn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Thin film thickness uniformity is crucial to get consistent film etch rate and device yield across the wafer. In the capacitive-coupled parallel plate PECVD system; the film thickness uniformity can be affected by many factors such as the heater temperature uniformity, the spacing between top and bottom electrode, RF power, pressure, gas flows and etc. In this paper, we studied how the PECVD SiN film thickness uniformity is affected by the substrate electrical conductivity and the RF power coupling efficiency. PECVD SiN film was deposited on 150-mm sapphire wafers in 200-mm Lam Sequel tool, fork marks were observed on the wafers. On the fork marks area SiN film thickness is thinner than that on the non-fork area. The forks are the wafer handler inside the process chamber to move the wafers from one station to another. The sapphire wafers and the ceramic forks both are insulator. The high resistivity of the sapphire wafers and the forks inhibits the RF power coupling efficiency during PECVD deposition, thereby reducing the deposition rate. Comparing between the high frequency and low frequency RF power (HFRF and LFRF respectively), the LFRF power coupling effect on the sapphire wafers is more dominant than the HFRF power on the film thickness. This paper demonstrated that the SiN thickness uniformity on sapphire wafers can be improved by depositing a thin TiW layer on the wafer before the SiN deposition. The TiW layer can be on the wafer surface, bottom or any layer before SiN deposition. <p class="card-text"><strong>Keywords:</strong> <a
