Patent ID: 6906395

Claim:
A micro-machined electromechanical system (MEMS) device comprising: an electromechanical device mechanism that is micro-machined in a semiconductor silicon wafer; an electrical signal carrier comprising electrically interconnected proximate, medial and distal portions that are submerged in a surface of the semiconductor silicon wafer with the proximate portion being interconnected to the electromechanical device mechanism, the interconnected proximate, medial and distal portions of the signal carrier further comprising a channel of dopant diffused into the surface of the semiconductor silicon wafer having a portion residing on a surface of the semiconductor silicon wafer that is in communication with the surface of the semiconductor silicon wafer over substantially the entire channel length and being electrically interconnected to the submerged portion; and a cover plate that is bonded to the surface of the semiconductor silicon wafer having the signal carrier and is bonded to a submerged portion of the signal carrier, the cover plate being structured to cover the device mechanism and the proximate portion of the signal carrier and to partially cover the submerged portion of the signal carrier.
