Patent ID: 7006276

Claim:
A microelectrical mechanical device comprising: (a) a substrate; (b) an arm having a first end anchored to the substrate and a free end extending over the substrate, the arm having a bottom surface facing the substrate and a top surface opposite the bottom surface and including at least one flex score extending across a least a portion of a width of the arm; (c) a reflector extending over the top surface of the free end of the arm; (d) an electrostatic activation electrode supported by the substrate and facing the bottom surface of the arm, the electrode, when activated by a first voltage, providing an electrical force sufficient to move the free end of the arm; and (e) an electrostatic lock, supported by the substrate and facing the bottom surface of the arm, the lock, when activated by a second voltage, providing an electrical force sufficient to hold the free end of the arm in position.
