Patent ID: 7417784

Claim:
A microelectromechanical systems (MEMS) device, comprising: a first electrode having a first surface; and a second electrode having a second surface facing the first surface, the second electrode movable in a gap between a first position and a second position, the first position being a first distance from the first electrode, the second position being a second distance from the first electrode, the second distance being greater than the first distance, wherein at least one of the electrodes comprises a porous layer having a porous surface facing the other of the electrodes, wherein the porous surface is substantially continuous while including a plurality of pores formed therethrough, wherein the second electrode comprises the porous layer, wherein the second electrode comprises an aluminum reflective layer, wherein the porous layer is directly under the reflective layer, wherein the second electrode further comprises a nickel layer, and wherein the aluminum reflective layer is interposed between the nickel layer and the porous layer.
