摘要： A semiconductor dynamic quantity sensor has a substrate including a semiconductor substrate, an insulation layer on a main surface of the semiconductor substrate, and a semiconductor layer on the insulation layer. The main surface has a projection that is trapezoidal or triangular in cross section. The semiconductor layer is divided by a through hole into a movable portion. A tip of the projection is located directly below the movable portion and spaced from the movable portion by a predetermined distance in a thickness direction of the substrate. A width of the tip of the projection is less than a width of the movable portion in a planar direction of the substrate. The distance between the tip of the projection and the movable portion is equal to a thickness of the insulation layer.

摘要： An oscillating angular speed sensor includes a detector, a driving portion, and a separating portion. When an angular speed is generated while the detector is driven to oscillate by the driving portion, Coriolis force is applied to the detector. Therefore, the angular speed is detected based on a capacitance variation in accordance with a variation of an interval between a movable electrode and a fixed electrode of the detector. The separating portion is distanced from the detector and the driving portion, and is configured to separate a first space accommodating the detector and a second space accommodating the driving portion.

摘要： An ultrasonic sensor device includes a substrate, a piezoelectric vibrator, and a Q-factor adjuster. The piezoelectric vibrator includes a pair of detection electrodes that face each other in a thickness direction of the substrate and a piezoelectric body interposed between the electrodes. The piezoelectric vibrator provides a membrane structure which is formed on a surface of the substrate and has rigidity lower than that of a remaining portion of the substrate. An ultrasonic wave is transmitted by the piezoelectric vibrator, and its reflected wave is received by the same piezoelectric vibrator. The Q-factor adjuster adjusts a Q-factor of the piezoelectric vibrator so that the Q-factor can be larger during a transmission period where the piezoelectric vibrator transmits the ultrasonic wave than during a reception period where the piezoelectric vibrator receives the ultrasonic wave.

摘要： A physical quantity sensor has a weight mass movable in a detection direction. Auxiliary capacitors are formed at both side ends of the weight mass in a non-detection direction by auxiliary movable electrodes and auxiliary fixed electrodes, respectively. When capacitances of the auxiliary capacitors change due to movement of the weight mass in the non-detection direction, a limiter circuit feedback-controls voltages applied to the auxiliary fixed electrodes to maintain the position of the weight mass unchanged. Thus, the weight mass is limited from moving in the non-detection direction thereby to improve accuracy in detection of the movement in the detection direction.
