    摘要: An angular velocity sensor includes a first gimbal portion, a second gimbal portion connected to the first gimbal portion by first torsion bars provided at opposing sides of the first gimbal portion, a frame portion connected to the second gimbal portion by second torsion bars provided at the opposing sides of the second gimbal portion, first electrostatic coupling portions provided at the opposing sides of the first gimbal portion to electrostatically couple the first gimbal portion and the second gimbal portion, and second electrostatic coupling portions provided at the opposing sides of the second gimbal portion to electrostatically couple the second gimbal portion and the frame portion. In the first gimbal portion, a maximum width of sides of a direction of the first torsion bars is greater than that of the sides where the first torsion bars are provided.

    摘要: A method is provided for making packaged micro-devices each including a micro movable element, a first packaging member formed with a recess, and a second packaging member formed with another recess. The micro movable element has a movable part. In accordance with the method, a device wafer is prepared for forming a plurality of micromovable elements. A first packaging wafer, formed with a plurality of recesses corresponding in position to the movable parts of the respective movable elements, is bonded to one surface of the device wafer. A second packaging wafer, formed with a plurality of recesses, is bonded to the other surface of the device wafer. The resulting laminate assembly is cut into separate products.

    摘要: A vibration sensor includes a vibration body, a drive circuit that vibrates the vibration body, a sense circuit that refers to a reference signal associated with a drive signal for the drive circuit and detects a physical state of the vibration body on the basis of a sense signal related to vibration of the vibration body, and a capacitor provided between the drive circuit and ground. The capacitor has a temperature characteristic of a capacitance value defined so as to compensate for at least a part of the temperature characteristic of a sensitivity of the sense signal to the vibration of the vibration body.
