    Abstract: A vibration gyroscope includes: a mass part supported to be displaceable in a first direction and a second direction; an exciter vibrating the mass part in the first direction; and a detector detecting a displacement amount of the mass part in the second direction. The first direction and the second direction are orthogonal to each other. A resonance frequency of the mass part in the first direction coincides with a resonance frequency of the mass part in the second direction. A Q-factor of vibration of the mass part in the second direction is smaller than a Q-factor of vibration of the mass part in the first direction.

  • Patent number: 8698315
    Abstract: 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.
