.... The commonality in MEMS devices with respect to FA is that the structures are free moving and have some electrical function. A useful framework for proceeding down a failure analysis flow is to first try to isolate the source of the failure to a) the MEMS, b) the electronics (ASIC or integrated circuitry), or c...
