Abstract: The present invention provides a microstructure device comprising multiple substrates with the components of the device formed on the substrates. In order to maintain uniformity of the gap between the substrates, a plurality of pillars is provided and distributed in the gap so as to prevent decrease of the gap size. The increase of the gap size can be prevented by bonding the pillars to the components of the microstructure. Alternatively, the increase of the gap size can be prevented by maintaining the pressure inside the gap below the pressure under which the microstructure will be in operation. Electrical contact of the substrates on which the micromirrors and electrodes are formed can be made through many ways, such as electrical contact areas, electrical contact pads and electrical contact springs.

Abstract: A spatial light modulator is disclosed, along with methods for making such a modulator. The spatial light modulator comprises an array of micromirrors each having a hinge and a micromirror plate held via a hinge on a substrate, the micromirror plate being attached to the hinge such that the micromirror plate can rotate along a rotation axis and the hinge structure is located between the micromirror plate and the light source. The mirror plate is formed between the hinge and the substrate on which the hinge is formed. As a result, the hinge is exposed to the incident light during the operation.

Abstract: A spatial light modulator comprises an array of micromirror devices each of which has a reflective and deflectable mirror plates. The mirror plates are moved between an ON and OFF state during operation, wherein the OFF state is a state wherein the mirror plate is not parallel to the substrate on which the mirror plate is formed. The micromirror device may have an ON state stopper for limiting the rotation of the mirror plate at the ON state angle, but does not have an OFF state stopper. The non-zero OFF state is achieved by attaching the mirror plate to a deformable hinge held by a hinge support that is curved at the natural resting state.

Abstract: Disclosed herein is method of operating a device that comprises an array of micromirrors. The method comprises a process usable for repairing stuck micromirrors of the micromirror array during the operation. The reparation process applies, at the ON state, two consecutive refresh voltages to the mirror plates of the micromirrors in the array with the pulses being separated in time longer than the characteristic oscillation time of the micromirrors. The reparation process can be applied independently to the micromirrors. Alternatively, the reparation process can be incorporated with a bias inversion process.

Abstract: A spatial light modulator is disclosed, along with methods for making such a modulator that comprises an array of mirror devices each having at least a first electrode and a second electrode. The first electrode is designated for driving the mirror plate of the micromirror device to an ON state, and the second electrode is designated for driving the mirror plate to an OFF state. The two electrodes can be disposed on the same side of the mirror plate but on opposite sides of the rotation axis of the mirror plate for driving the mirror plate to rotate in opposite directions. Alternatively, the two electrodes can be disposed on the opposite sides of the mirror plate, but on the same side of the rotation axis of the mirror plate for driving the mirror plate to rotate in opposite directions. The ON state and OFF state of the mirror plate can be defined by stops. The stops may be formed on substrate(s), hinge structures holding the mirror plates of the micromirror device and/or a desired location within the micromirror device. Alternatively, the electrodes for the ON state and the OFF state can be used as stops, either individually or in combination, or in combination with other component(s), such as substrate(s) of the micromirror device. The OFF state angle and the ON state angle are preferably different.

Abstract: A micromirror array comprises micromirrors of different properties for use particularly in display systems. Micromirrors of different properties can be arranged within the micromirror array according to a predetermined pattern, or randomly. However, it is advantageous to arrange the micromirrors with different properties within the micromirror array neither in complete order nor complete in random.
