Patent ID: 6969630

Claim:
A method of forming an electromechanical device comprising the steps of: fabricating a first beam and an integrated circuit monolithically on a semiconductor substrate using standard semiconductor process flows; patterning above the first beam a sacrificial material; fabricating a second beam by performing the steps of: depositing a first conductive material on the sacrificial material by means of sputtering or evaporation; patterning a sacrificial mold for a second conductive layer; electrodepositing a thick second conductive layer over the mold; removing the sacrificial mold and an excess amount of the first conductive layer underneath the mold; depositing and patterning a mechanical support layer on top of the device; patterning and etching the semiconductor substrate from a backside of the substrate; and releasing the first beam so as to be movable by removing the sacrificial material on top of the first beam to form an air cavity above the first beam, the first beam being attached to the substrate at one or more points.
