    摘要: A micromirror array fabricated on a semiconductor substrate. The array is comprised of three operating layers. An addressing layer is fabricated on the substrate. A hinge layer is spaced above the addressing layer by an air gap. A mirror layer is spaced over the hinge layer by a second air gap. The hinge layer has a hinge under and attached to the mirror, the hinge permitting the mirror to tilt. The hinge layer further has spring tips under the mirror, which are attached to the addressing layer. These spring tips provide a stationary landing surface for the mirror.

    摘要: A method of resetting the cells of a spatial light modulator (FIG. 11). A saturation voltage pulse is applied, causing the cells to achieve a fully saturated state in a given amount of time. A reset pulse of opposite polarization than the saturation voltage pulse is then applied, driving the cells toward the opposite fully saturated state. The reset pulse is removed after the same amount of time, causing the cells to assume their relaxed state in the same amount of time it took them to achieve their fully saturated state.

    摘要: An improved hinge (12) for a micro-mechanical device (10). The hinge is fabricated from alternating layers (12a, 12b) of different materials. A first material is selected on the basis of its amenability to fabrication processes and a second material is chosen for its strength, or some other desired characteristic, relative to the first material.
