Patent ID: 6949807

Claim:
A hermetically sealed MEMS device, comprising: a first cover plate having a first internal portion structured to cooperate with a micro-machined electromechanical device and formed with a pass-through window positioned at a second internal portion different from the first internal portion; a micro-machined electromechanical device patterned in a layer of semiconductor silicon material and arranged relative to the cooperating first internal portion of the cover plate; an internal seal device patterned in the layer of semiconductor silicon material and sized larger than the pass-through window, the internal seal device being joined to an internal surface of the cover plate in a sealing arrangement with the window and having an external surface area exposed in the window; an internal electrical conductor arranged in electrical connection between the micro-machined electromechanical device and the internal seal device; and an external electrical conductor arranged in electrical connection with the external surface area of the internal seal device exposed in the window.
