A detailed analysis of semiconductor processing technologies that form the basis for the physical realization of all semiconductor based device applications; from the realization of very large and ultra scale integrated circuits (VLSICs, ULSICs) and complex system-on-chip (SoC) application specific integrated circuits (ASICs) to individual device research and development in photonics, photonic integrated circuits (PICs), micro-electro-mechanical-systems (MEMS), etc. The primary objective of this course is to provide students with the fundamental understanding of standard unit processes involved in microfabrication, enforcing their experience with implementation projects in a microfabrication laboratory, and providing familiarity with basic microfabrication tools. Although considerable focus will be given to Si-based microfabrication technologies, primarily because of its dominance in microelectronic industry today, the course material will be enriched with the cutting-edge compound semiconductor technologies (specifically GaAs/AlGaAs and InP/InGaAsP technologies) to provide a sound foundation for general semiconductor based fabrication, research and development.
