PROBLEM TO BE SOLVED: To provide a method of manufacturing a microstructure. SOLUTION: The method of manufacturing the microstructure includes that: a first structure part is formed on a substrate; a sacrificial material is arranged on the first structure part; a layer of a first structure material is deposited on the sacrificial material and the substrate; and a second structure part is formed on the layer of the first structure material by removing at least a part of the sacrificial material, wherein the second structure part is connected to the substrate and movable between the first position at which the second structure part is separated from the first structure part and the second position at which the second structure part is made contact to the first structure part, the stiction between the second structure part and the first structure part is reduced by forming a carbon layer on at least one of the surfaces of the second structure part and the first structure part.

Abstract:
PROBLEM TO BE SOLVED: To provide a microstructure used for a space light modulator or the like. SOLUTION: The method comprises forming a substrate with a first structure part having the first height and a second structure part having the height higher than the first height, and accumulating a sacrificial material such as polyarylenes and hydrogen silsesquioxane on the substrate. In this case, the sacrificial material covers at least the first structure part, the layer of the first structure material is accumulated on the first sacrificial material, and an opening part is formed in the layer of the first structure material. The opening part provides an access from outside to the first sacrificial material located under the layer of the first structure material. Further, a third structure part connecting with the second structure part is formed by eliminating the first sacrificial material, and at least a part of the third structure part exist above the first structure part.

PROBLEM TO BE SOLVED: To provide a high-resolution scanning display system. SOLUTION: The display system includes: one or more rows of tiltable micro mirrors, each of which is configured to be selectively tilted to an "on" position to reflect incident light in an "on" direction and to be selectively tilted to an "off" position to reflect incident light in an "off" direction; and an optical projection system configured to project light reflected by the micro mirrors in the "on" direction to produce one or more first lines of image pixels along a first direction in a display image and to change the direction of the light reflected by the micro mirrors in the "on" direction to produce one or more second lines of image pixels in the display image. The one or more second lines of image pixels are substantially parallel to the one or more first lines of image pixels. COPYRIGHT: (C)2008,JPO&INPIT

Abstract:
PROBLEM TO BE SOLVED: To provide a high-contrast spatial light modulator for a preferable display and printing. SOLUTION: A spatial light modulator includes a mirror plate (102), comprising a reflective upper surface, a lower surface (103) having a conductive surface portion, and a substrate portion having a first cavity that has an opening on the lower surface, a second cavity in the substrate portion, and a membrane over the second cavity. The modulator includes a substrate (300) comprising an upper surface, a hinge support post (105) in connection with the upper surface, a hinge component, supported by the hinge support post and in connection with the mirror plate that facilitates rotation of the mirror plate. The hinge component extends into the inside of the first cavity. An upright landing tip (222) is configured to contact the membrane over the second cavity in the substrate portion of the mirror plate, to stop the rotation of the mirror plate at a predetermined orientation.
