    Abstract: A structure having a first movable portion displaced perpendicular to a substrate surface and a second movable portion displaced parallel to the substrate surface is realized by a laminated structure employing a nested structure for the first portion and the second portion. The laminated structure is provided with inner and outer movable portions. A y spring is connected to the outer portion, and the outer portion is supported in a y-axis direction by the y spring at a height apart from an outer substrate. A z spring is connected to the inner portion, and the inner portion is supported in a z-axis direction by the z spring at a height apart from the outer substrate. The outer portion and the z spring are at different heights from the substrate, and the z spring overpasses across the outer portion at a height apart from the outer movable portion.

  • 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.
