    摘要: A method of fabricating micro-mechanical devices. A mesa is etched in a homogeneous wafer. The wafer is bonded to a patterned substrate with the mesa defining device elements suspended above the substrate. A portion of the wafer is removed until a desired device thickness is achieved. Discrete elements of the device are then formed by performing a structural etch on the remaining wafer material.

    摘要: Dynamic balancing reduces quadrature bias in microfabricated vibrating instruments such as tuning fork gyros so that a purity of motion is achieved in the absence of any angular rate input. Balancing is achieved by ablating (74) or depositing (72) onto support structure (62) for a tuning fork gyroscope rather than the proof mass (60) itself by melting and moving material on a tuning fork beam (62). Such adjusting is advantageously done during actual operation of the gyro by laser beam application through an encapsulating transparent cover which can be either part of the chip die or an external package.

    摘要: A micromechanical accelerometer comprises a mass of monocrystalline silicon in which a substantially symmetrical plate attached to a silicon frame by flexible linkages is produced by selective etching. The plate has a plurality of apertures patterned and etched therethrough to speed further etching and freeing of the plate and flexible linkages, suspending them above a void etched beneath. The plate is capable of limited motion about an axis created by the flexible linkages. An accelerometer comprised of a substantially symmetrical, linkage supported plate configuration is implemented as an angular accelerometer paired with an auxiliary linear accelerometer, which is used to compensate for the linear sensitivity of the angular sensor, to achieve an instrument that is insensitive to linear acceleration and responds to angular acceleration.

    摘要: A micro machined micro pump capable of flow rates on the level of microliters per minute formed by micro machining of a semiconductor material such as silicon with a set of channels or passages and having a semiconductor membrane interacting with the pattern of channels and passages and under selective control of activating means to induce traveling wave type motion of said membrane that creates pump action between inlet and outlet ones of the passages. To induce the pump action motion of the membrane electrical conductors can be applied to the membrane in a pattern which, when selectively activated interact with an electric or magnetic field to produce such motion. Alternatively piezolelectric or other electrostrictive mechanisms may be employed to induce the appropriate membrane motion.
