Claim Text:
1. A Microelectromechanical System (MEMS), comprising: a substrate; a released proof mass disposed over a first area of the substrate and having: a first body region comprising a thick metal layer; and a first sensing structure comprising a thin metal layer, but lacking the thick metal layer, wherein the thick metal layer has a film thickness that is at least three times greater than that of the thin metal layer; and a frame disposed over a second area of the substrate, the frame having: a second body region comprising at least one of the metal layers; and a second sensing structure comprising the thin metal layer, but also lacking the thick metal layer, and separated from the first sensing structure by a gap to permit a change in displacement of the released proof mass relative to the frame.
