Abstract :
The paper reviews the state-of-the-art in the field of CMOS-based microelectromechanical systems (MEMS). The different CMOS MEMS fabrication approaches, pre-CMOS, intermediate-CMOS, and post-CMOS, are summarized and examples are given. Two microsystems fabricated with post-CMOS micromachining are presented, namely a mass-sensitive chemical sensor for detection of organic volatiles in air and a 10-cantilever force sensor array for application in scanning probe microscopy. The paper finishes with a look into the future, discussing key challenges and future application fields for CMOS MEMS.
