Abstract:

My talk will discuss current research in the fabrication technologies to make the final "S" in MEMS (it stands for "Systems") a reality. These processes either use unmodified CMOS wafers as the starting material, or use micromachined fragments of CMOS as microsystems components. The range of processes that are compatible with CMOS post-processing has expanded recently, with the addition of LPCVD poly-SiGe as a promising microstructural material to existing capabilities in dry etching of the silicon substrate. Microassembly processes are mandatory for microsystems that combine silicon, opto-electronic, micromechanical, and even microfluidic components. Major hurdles that must be addressed are the need for high-quality mechanical and electrical interfaces after assembly.
