The shift from ceramic to laminate substrates for packaging central processing unit (CPU) microprocessors facilitated this migration to organic substrates by providing a volume application that enabled the technology to mature faster.

In particular, the design and development of photoresists that are sensitive to short exposure wavelengths have enabled the industry to migrate to smaller device sizes. Photoresist allows precise pattern formation upon exposure to light through a template called a photomask and subsequent etching of portions of the photoresist, resulting in the permanent transfer of patterns to the wafer substrate. </div></td></tr><tr><td valign="top"><img src="/web/20140626132011im_/http://www.semi.org/sites/semi.org/files/cms/fragments//semi_en_idoc_dynamic_list/moecicon.gif" alt="Member Only Content" hspace="0" vspace="2" border="0"/></td><td><div style="font-size: 12px;"><a href="https://web.archive.org/web/20140626132011/http://ams.semi.org/ebusiness/CustomerService/MemberDownloadDocument.aspx?ID=1700">SEMI Materials Brief: Prime Polished Silicon Wafers (PDF)</a><br/>A wafer is a thin slice of semiconducting material upon which microcircuits are constructed by doping (via diffusion or ion implantation), chemical etching, and deposition of various materials. </div></td></tr><tr><td valign="top"><img src="/web/20140626132011im_/http://www.semi.org/sites/semi.org/files/cms/fragments//semi_en_idoc_dynamic_list/moecicon.gif" alt="Member Only Content" hspace="0" vspace="2" border="0"/></td><td><div style="font-size: 12px;"><a href="https://web.archive.org/web/20140626132011/http://ams.semi.org/ebusiness/CustomerService/MemberDownloadDocument.aspx?ID=1712">SEMI Materials Brief: Semiconductor Photoresist Removers (PDF)</a><br/>Removal Materials are wet chemical solutions used to remove the photoresist left on the wafer after processing as well as for cleaning wafers immediately after etch processes on aluminum (Al), tungsten (W), titanium (Ti), titanium nitride (TiN), dielectric oxides, and polysilicon surfaces.

Prior to the 1990s Chemical Mechanical Planarization (CMP) was looked on as too "dirty" to be included in high-precision fabrication processes, since abrasion tends to create particles and the abrasives themselves are not without impurities. However, given the small size and complexity of today’s advanced semiconductor devices, it is essential that these layers be extremely flat for lithographic processing.
