    摘要: When forming a trench of a narrow width in a thick semiconductor layer, a trench can be formed without the occurrence of semiconductor residue. In this Specification, a semiconductor device in which a trench is formed in a semiconductor layer is disclosed. In the semiconductor layer of the semiconductor device, a compensation pattern which compensates for sudden changes in the width of the trench is formed at a place at which the width of the trench changes suddenly. In the semiconductor layer of the above-described semiconductor device, since a compensation pattern is formed at a place at which the trench width changes suddenly, in the case where forming the trench using a deep RIE method, the occurrence of steep inclined portions arising from semiconductor residue can be prevented. Consequently, when forming a trench of a narrow width in a thick semiconductor layer, the occurrence of semiconductor residue can be prevented.

    摘要: The micro device includes a support substrate, and a movable structure configured to move with respect to the support substrate. At least one of the support substrate and the movable structure is provided with at least one protrusion protruding towards the other of the support substrate and the movable structure. Further, a base portion extending into the one of the support substrate and the movable structure is provided integrally with the at least one protrusion. With this configuration, the protrusion is securely held by the base portion, and the detachment of the protrusion can therefore be prevented even after repeated collisions between the support substrate and the movable structure via the protrusion.

    摘要: A microphone that identifies the direction along which acoustic waves propagate with one diaphragm, and has superior durability is provided. The microphone includes a circular diaphragm supported at a center portion thereof. When the diaphragm receives acoustic waves, each position around the center thereof will vibrate with a phase depending upon the direction of the acoustic waves. First electrodes are arranged on one surface of the diaphragm and second electrodes are arranged facing corresponding first electrodes to form a first capacitor. Third electrodes are arranged on the other surface of the diaphragm and fourth electrodes are arranged facing corresponding third electrodes to form a second capacitor. A controller applies a voltage to the second capacitors so that the capacitance of the first capacitors will be constant and identifies the direction along which the acoustic waves propagate based on the difference in the voltages applied to each of the second capacitors.

    摘要: In a semiconductor strain detector, the temperature characteristic of the output of a zero-point temperature compensating circuit is added to the zero-point temperature characteristic of the output of a bridge circuit composed of strain gauges, to perform a zero-point temperature compensation of the final output. Further, two kinds of diffusion resistors having different surface impurity densities are used in each amplifying circuit to perform a sensitivity-temperature compensation in which a temperature coefficient of sensitivity is considered up to the second-order term.

    摘要: A microphone that may identify the direction along which acoustic waves propagate with one diaphragm, and which has superior durability is provided. The microphone comprises a circular diaphragm. The diaphragm is supported at the center portion thereof. When the diaphragm receives acoustic waves, each position around the center thereof will vibrate with a phase depending upon the direction of the acoustic waves. First electrodes are arranged on one of the surfaces of the diaphragm. Second electrodes are arranged so that each second electrode faces corresponding first electrode with gap. Each first electrode and corresponding second electrode facing thereto form a first capacitor. Third electrodes are arranged on the other surface of the diaphragm. Fourth electrodes are arranged so that each fourth electrode faces corresponding third electrode with gap. Each third electrode and corresponding fourth electrode facing thereto form a second capacitor. The controller applies a voltage to each of the second capacitors so that the capacitance of each of the first capacitors will be a constant value. The controller identifies the direction along which the acoustic waves propagate based on the difference in the voltages applied to each of the second capacitors. Vibration of the diaphragm will be inhibited by the voltages applied to the second capacitors while the direction is identified based on the voltages. The durability of the diaphragm can be improved.
