    摘要: The present invention relates to a Sub-threshold Field Effect Transistor (SF-FET). The invention integrates a MEMS mechanical transducer along with the sensing mechanism in a single device. Forced mass is capacitively coupled onto the FET structure. Dielectric SiO2 forms good interface with underlying silicon substrate. Air dielectric forms second dielectric wherein effective gate capacitance is the series combination of the second dielectric capacitance and fixed dielectric. Inertial displacements are sensed by observing change in drain current (ID) of the sensor due to change in gap height (T Gap) of the second dielectric of the sensor caused by forced mass.

    摘要: A micromovement measuring device has a first element such as a probe tip or flat plate coupled to a test body (107) the movement of which is to be measured. A second element (104) is located adjacent to the first element, to form a gap (108) therebetween. As the test body and the first element gradually move away from the measuring element, so increasing the size of the gap, the second element is repeatedly moved up, to restore the gap to its original size. These repeated small quantized movements of the measuring element (104) are counted, and are used to provide an indication of how far the test body (107) has moved. In other embodiments, the first element may gradually move toward the second element, with the latter repeatedly moving away.

    摘要: A micromechanical micromotion amplifier has an integrated structure formed primarily of silicon and comprises a plurality of long slender flexible beams which are released from a silicon substrate for movement with respect to fixed points of reference upon the substrate. By arranging these beams in cooperating perpendicular pairs as micromotion amplifier stages, an input axial force/movement applied to a moveable free end of a first beam generates a transverse motion or buckling movement which in turn, translates or induces buckling movement in the connected second beam. The resultant output buckling of the second beam is an order of magnitude greater than the initial movement applied as an input to the first beam. Thus, beam pairs can be arranged as micromotion amplifier stages to amplify minute amounts of movement. Beam pairs or stages can also be cascaded to form integrated devices capable of producing greatly increased measurable effects in response to minute amounts of input. Such devices are useful as highly sensitive integrated micro-sensors for measuring a wide variety of parameters such as temperature, pressure, humidity, impact or acceleration. Such devices may also form the basis of highly sensitive micro-switches.

    摘要: Various structures for cantilever beam tunneling rate gyro devices formed on a single substrate are disclosed. A cantilever electrode having a plurality of portions extending from the substrate with one end of the cantilever is suspended above the substrate at a distance from a tunneling electrode so that a tunneling current flows through the cantilever and tunneling electrode in response to an applied bias voltage. The cantilever and tunneling electrodes form a circuit that produces an output signal. A force applied to the sensor urges the cantilever electrode to deflect relative to the tunneling electrode to modulate the output signal. The output signal is a control voltage that is applied between the cantilever electrode and a control electrode to maintain a constant tunneling current. In the preferred embodiment, two cantilever portions extend from the wafer surface forming a Y-shape. In a further embodiment, a strap is fabricated on the cantilever electrode. In an alternate embodiment, a ridge emitter is formed such that it remains under the cantilever electrode during lateral motion of the cantilever. In an alternate embodiment, a cantilever having a varying width is fabricated.
