Patent ID: 8680955

Claim:
A micro-electromechanical systems (MEMS) switch having a thermally neutral anchor configuration comprising: a substrate; a first conductive anchor coupled to the substrate; a second conductive anchor spaced from the first conductive anchor and coupled to the substrate; a conductive cantilever beam having a first end portion situated between and coupled to the first conductive anchor and the second conductive anchor, a second end portion suspended over the substrate, and a middle portion between the first end portion and the second end portion; and a conductive actuator plate formed on the substrate at a location beneath the middle portion of the conductive cantilever beam; and wherein the conductive cantilever beam has a longitudinal axis and wherein: a first rotation axis for the conductive cantilever beam is formed between the first conductive anchor and the first end portion of the conductive cantilever beam and a second rotation axis for the conductive cantilever beam is formed between the second conductive anchor and the first end portion of the conductive cantilever beam during thermal expansion of: the conductive cantilever beam and the first conductive anchor and the second conductive anchor, wherein the first and second rotation axes are parallel to the longitudinal axis of the conductive cantilever beam.
