摘要： A microminiature moving device has disposed on a single-crystal silicon substrate movable elements such as a movable rod and a movable comb electrode that are displaceable in parallel to the substrate surface and stationary parts that are fixedly secured to the single-crystal silicon substrate with an insulating layer sandwiched between. Depressions are formed in the surface regions of the single-crystal silicon substrate where no stationary parts are present and the movable parts are positioned above the depressions. The depressions form gaps large enough to prevent foreign bodies from causing shorts and malfunctioning of the movable parts.

摘要： An optical device formed on a substrate comprises: plural fiber channels formed in the top surface of the substrate; a mirror to be pushed into and pulled out of an optical path between optical fibers disposed in the fiber channels; a movable rod carrying at one end the mirror; a comb-type electrostatic actuator disposed in association with the intermediate portion of the movable rod, for moving the movable rod lengthwise thereof; and plural support beams disposed near the one and the other end of the movable rod on both sides of the point of application of driving force by the comb-type electrostatic actuator, for movably supporting the movable rod. The support beams support the movable rod at positions having line symmetry with respect to a center line parallel to the lengthwise direction of the movable rod, and points of supporting the movable rod by the plural support beams are symmetrical with respect to the point of application of the driving force by the comb-type electrostatic actuator. Even if the driving force by the comb-type electrostatic actuator contains a vector component of a direction different from the desired one in which to drive the movable rod, it is possible to suppress movement of the movable rod in other directions than the desired one to drive the movable rod.

摘要： A movable part formed on a substrate and adapted to be displaced in a direction parallel to the sheet surface of the substrate, a fixing part formed and fixedly mounted on the substrate, and springy hinges extending parallel to the sheet surface of the substrate and having their opposite ends connected to the movable part and the fixing part for supporting the movable part in a displaceable manner are provided. As viewed in cross section in a plane perpendicular to the lengthwise direction of the hinges, the hinge has a width which is diminishing as the top surface of the substrate is approached, thus having a trapezoidal or triangular cross section. A width as measured on the top surface of the hinge which is required to provide an equivalent spring constant can be chosen to be greater than the width of a hinge having a rectangular cross section (constant width), and this facilitates the implementation of the photolithography during the manufacture.

摘要： A miniature movable device comprises a movable part (a mirror, a movable rod, support arms, and a movable comb tooth electrode) formed on a substrate and adapted to be displaced in a direction parallel to the sheet surface of the substrate, a fixing part formed and fixedly mounted on the substrate, and hinges, each having its opposite ends connected to the movable part and the fixing part and assuming two flexural conditions which are reversed in flexural, the hinges being effective to maintain the movable part at two positions by a self-holding action when it assumes either flexural condition. The substrate is formed with wall surfaces which are disposed oppositely to the opposite surfaces of the hinges over a movable range of the hinges. Spacings between the hinges and the wall surfaces disposed on the opposite sides thereof are equal to each other at every point along the lengthwise direction of the hinges when the hinges assume one of the two flexural conditions (an initial condition assumed upon manufacture). This eliminates an inconvenience that during a drying step which follows a wet etching operation during the manufacture, a liquid may remain on only one side of the hinges to cause the hinges to be held attracted to the wall surfaces.

摘要： A micro-optic device including a complicate structure and a movable mirror is made to be manufactured in a reduced length of time. A silicon substrate and a single crystal silicon device layer with an intermediate layer of silicon dioxide interposed therebetween defines a substrate on which a layer of mask material is formed and is patterned to form a mask having the same pattern as the configuration of the intended optical device as viewed in plan view. A surface which is to be constricted as a mirror surface is chosen to be in a plane of the silicon crystal. Using the mask, the device layer is vertically etched by a reactive ion dry etching until the intermediate layer is exposed. Subsequently, using KOH solution, a wet etching which is anisotropic to the crystallographic orientation is performed with an etching rate which is on the order of 0.1 μm/min for a time interval on the order of ten minutes is performed to convert the sidewall surface of the mirror into a smooth crystallographic surface. Subsequently, the intermediate layer is selectively subject to a wet etching to remove the intermediate layer only in an area located below the movable part of the optical device.
