Patent ID: 7535620

Claim:
A micro-electro-mechanical system (MEMS) micro mirror, comprising: a body having a mirror support, opposed anchors, and flexible hinges which connect the mirror support to the anchors; the mirror support having a mirror support surface, a first comb edge, a second comb edge opposed to the first comb edge, and comb fingers formed in a layer of silicon on insulator (SOI) extending outwardly from each of the first comb edge and the second comb edge; a first fixed electrode spaced from the first comb edge of the mirror support and having comb fingers formed in the layer of silicon on insulator extending outwardly toward the mirror support to interact with the comb fingers on the first comb edge and interlace upon movement of the mirror support of the body in a first direction about the flexible hinges, prior to being energized the comb fingers along the first comb edge being positioned on one horizontal plane and the comb fingers of the first fixed electrode being on another horizontal plane; a second fixed electrode spaced from the second comb edge of the mirror support and having comb fingers formed in the layer of silicon on insulator extending outwardly toward the mirror support to interact with the comb fingers on the second comb edge and interlace upon movement of the mirror support of the body in a second direction about the flexible hinges, prior to being energized the comb fingers along the second comb edge being positioned on one horizontal plane and the comb fingers of the second fixed electrode being on another horizontal plane.
