Patent ID: 6995894

Claim:
A micromirror, comprising: an upper plate, comprising, a rotatable mirror rotatable in an X-axis direction for reflecting an incident light at a predetermined angle, rotatable beams around the rotatable mirror each connected to the rotatable mirror for rotating in a Y-axis direction together with the rotatable mirror, and magnetic films formed on the rotatable mirror and the rotatable beams, respectively; and a lower plate, comprising, a substrate, magnetic coils formed on the substrate opposite to respective magnetic films for rotating the rotatable mirror or the rotatable beams, or both the rotatable mirror and the rotatable beams, depending on a voltage provided thereto, and supporting posts formed on the substrate; wherein the rotatable beams are directly attached to the supporting posts with hinges so as to enable rotation of the rotatable mirror and the rotatable beams together in the Y-axis direction, and wherein a height of the supporting posts determine a size of an air gap between the substrate and the upper plate.
