Abstract

Silicon-compatible micromachining provides a lowcost monolithic solution for the integration of microelectromechanical systems (MEMS). In the last years,CMP (the French MultiProject Wafer Service) hasmade available technological solutions for the fabrication of CMOS-compatible MEMS. Numerous monolithic devices have been fabricated using this service.The inspection of failed devices has allowed the identification of the most typical failure mechanisms anddesign errors for this type of MEMS. This valuable information, together with a detailed analysis of the fabrication processes, is used in this paper to provide a classification of faults in silicon-compatible MEMS whichcan later be used for fault simulation and testing.
