Abstract:
1. A method for fabricating a micro-electromechanical systems (MEMS) device having a top cap and an upper sense plate, said method comprising: producing a device wafer including an etched substrate, etched silicon, and interconnect metal, a portion of the interconnect metal being bond pads; adding a metal wraparound layer to a back side, edges, and a portion of a front side of the device wafer; producing an upper wafer including an etched substrate and interconnect metal; bonding the device wafer and the upper wafer; and dicing the bonded upper wafer and device wafer into individual MEMS devices, wherein producing the device wafer includes forming a support ring around a perimeter of the MEMS device components, the support ring arranged to support the upper wafer.
