Patent ID: 7605964

Claim:
An array of micromirrors with non-fixed underlying structures having a plurality of micromirrors comprising: a) a bottom layer having control circuitry; b) a micromirror having a top side and a bottom side, wherein the top side has a reflective surface; and c) underlying structures for providing actuation force and restoration force for motion of the micromirror and generating the micromirror motions; wherein the underlying structures are aligned with a principal rotation of the micromirror motion and wherein the underlying structures comprise: a) at least one bottom electrode to provide electrostatic actuation force; b) at least one flexible structure to provide restoration force for the micromirror; and c) at least one post structure connecting and supporting the underlying structures and the micromirror; wherein the underlying structures of each micromirror is individually oriented and aligned during fabrication process to generate a single principal rotational motion for forming a desired surface profile.
