Patent ID: 7723144

Claim:
A package for a micro-electromechanical device, the package comprising: a substrate having an upper surface, a lower surface, a first side surface, and a second side surface of the substrate; the substrate adapted to support the micro-electromechanical device on the upper surface, the micro-electromechanical device being electrically coupled to a plurality of electrodes disposed on the upper surface of the substrate; a thermally conductive structure coupled to the lower surface of the substrate; a dielectric layer disposed adjacent to the thermally conductive structure, the dielectric layer having a first surface and a second surface, wherein a portion of the first surface of the dielectric layer is in contact with the thermally conductive structure; an electrical contact layer having a plurality of traces in electrical communication with the plurality of electrodes, a first portion of the electrical contact layer being disposed on the first side surface of the substrate and a second portion of the electrical contact layer disposed over the second surface of the dielectric layer; an interposer structure coupled to the substrate, wherein the interposer structure includes a continuous annular region defining a recessed region bounded by a bond surface; and a transparent cover coupled to the interposer structure and sealing the micro-electromechanical device in the recessed region to isolate the micro-electromechanical device in a controlled environment.
