Abstract:
A method of supporting a product wafer for etching of microelectromechanical system (MEMS) devices through a first side of the product wafer utilizing a patterned handle wafer, the method comprising:forming a first structure pattern on a first side of the handle wafer; forming a second structure pattern on a second side of the product wafer; patterning a plurality of MEMS devices on the first side of the product wafer; and positioning the product wafer on the handle wafer with the second side of the product wafer facing the first side of the handle wafer wherein the first structure pattern of the handle wafer mates with the second structure pattern of the product wafer in a mechanical connection that limits lateral movement between the product wafer and the handle wafer; and etching the plurality of MEMS devices patterned on the product wafer using a through-etching process such that the MEMS devices are released from the product wafer.
