Abstract

A process for fabricating a MEMS device is disclosed. The device has at least one hinged element. The MEMS device including the hinged element is delineated and defined on a semiconductor substrate. The substrate is placed device side down in a chamber. The MEMS device is then exposed to a release expedient for sufficient amount of time for the release expedient to dissolve a sacrificial material connecting the element to the substrate. Upon the dissolution of the sacrificial material, the element is released from the substrate and pivots away from the surface.
