    Abstract: The present invention relates to a fabrication process for manufacture of micro electromechanical (MEM) devices such as cantilever support beams. This fabrication process requires only two lithographic masking steps and offers moveable electromechanical devices with high electrical isolation. A preferred embodiment of the process uses electrically insulating glass substrate (102) as the carrier substrate and single crystal silicon (108) as the MEM component material.
    The process further includes deposition of an optional layer of insulating material (110) such as silicon dioxide on top of a layer of doped silicon (108) grown on a silicon substrate. The silicon dioxide (110) is epoxy bonded to the glass substrate (102) to create a silicon-silicon dioxide-epoxy-glass structure (200). The silicon is patterned using anisotropic plasma dry etching techniques. A second patterning then follows to pattern the silicon dioxide layer (110) and an oxygen plasma etch is performed to undercut the epoxy film (120) and to release the silicon MEM component. This two-mask process provides single crystal silicon MEMs with electrically isolated MEM component. Retaining silicon dioxide insulating material (110) in selected areas mechanically supports the MEM component.
