The International Symposium on Ultra-Clean Processing of Semiconductor Surfaces (UCPSS) is a bi-annual conference which has been organized by IMEC since 1992.
Volume is indexed by Thomson Reuters CPCI-S (WoS).
The scope of the symposium includes all issues related to contamination, cleaning and surface preparation in mainstream large-scale Integrated Circuit manufacture. At first, silicon was typically the main semiconductor of interest. As other semiconducting materials such as SiGe, SiC, Ge and III-V compounds came under consideration for future devices, the scope was broadened so as to include these materials. Parallelling the fast-moving CMOS industry, the photovoltaic industry has also recognized the need to make improvements in cleaning. Moreover, in order to promote these semiconductor cleaning activities in PV, it was decided to add a special session focused on this topic.
