Patent ID: 6996306

Claim:
A micro-optical device comprising: a reflective movable micro-mirror connected with comb finger electrodes and springs via a shuttle beam; a set of suspended springs connected with said shuttle beam and with one end anchored onto a substrate; a comb drive actuator consists a set of movable comb finger electrodes suspended on a substrate and connected with said shuttle beam, and a set of stationary comb finger electrodes anchored on said substrate; and the shuttle beam being movable with respect to the stationary portion of said substrate in response to operation of said comb drive actuator, thereby said micro-mirror is moved by said shuttle beam, wherein the set of suspended springs has a thickness that is less than a thickness of each of the set of movable comb finger electrodes and the set of stationary comb finger electrodes in a perpendicular out-of-plane direction to said substrate of the device.
