    摘要: A surface micromachined micromagnetic actuator is provided with a flap capable of achieving large deflections above 100 microns using magnetic force as the actuating force. The flap is coupled by one or more beams to a substrate and is cantilevered over the substrate. A Permalloy layer or a magnetic coil is disposed on the flap such that when the flap is placed in a magnetic field, it can be caused to selectively interact and rotate out of the plane of the magnetic actuator. The cantilevered flap is released from the underlying substrate by etching out an underlying sacrificial layer disposed between the flap and the substrate. The etched out and now cantilevered flap is magnetically actuated to maintain it out of contact with the substrate while the just etched device is dried in order to obtain high release yields.

    摘要: A method for fabricating a module for at least partially intercepting a light beam propagating along a beam path includes providing a single crystal silicon substrate with a first substrate surface and a second substrate surface. The method further includes forming a reflector support layer on the first substrate surface. The method further includes forming a support frame and at least one reflector by etching the substrate from the second substrate surface. The method further includes forming at least one electrical conduit on the reflector support layer. The method further includes forming a reflector support by etching the reflector support layer from the first substrate surface, the reflector support mechanically coupled to the support frame and the reflector, the reflector support movable such that the reflector is movable substantially perpendicularly to the first substrate surface.
