Patent ID: 7202560

Claim:
A single integrated wafer package comprising: a micro electromechanical system (MEMS) wafer with a first surface, the MEMS wafer having at least one MEMS component on its first surface: an active device wafer with a first surface, the active device wafer having an active device circuit on its first surface and configured to be spaced apart from the MEMS wafer such that the first surface of the MEMS wafer faces the first surface of the active device wafer; a seal ring adjacent the first surface of the MEMS wafer such that a seal is formed about the MEMS component by at least the combination of the seal ring and the first surface of the MEMS wafer; and an external contact to the single integrated wafer package, wherein the external contact accessible externally to the single integrated wafer package and is electrically coupled to the active device circuit of the active device wafer.
