Patent ID: 10273147

Abstract:
A MEMS and a method of manufacturing MEMS components are provided. The method includes providing a MEMS wafer stack including a top cap wafer, a MEMS wafer and optionally a bottom cap wafer. The MEMS wafer has MEMS structures patterned therein. The MEMS wafer and the cap wafers include insulated conducting channels forming insulated conducting pathways extending within the wafer stack. The wafer stack is bonded to an integrated circuit wafer having electrical contacts on its top side, such that the insulated conducting pathways extend from the integrated circuit wafer to the outer side of the top cap wafer. Electrical contacts on the outer side of the top cap wafer are formed and are electrically connected to the respective insulated conducting channels of the top cap wafer. The MEMS wafer stack and the integrated circuit wafer are then diced into components having respective sealed chambers and MEMS structures housed therein.
