Patent number: 6151966Abstract: A semiconductor accelerometer device is formed on an SOI substrate by micro-machining. A movable unit is supported at both ends, and a weight portion is movable in response to acceleration exerted in the detection direction. A movable electrode is formed in a comb shape integrally with the weight portion. A pair of fixed electrodes in a comb shape are cantilevered and interleaved with the movable electrode to face the movable electrode. A plurality of through holes is provided in the electrodes so that the electrodes have Rahmen structure which is a series of rectangular frames. This structure reduces the weight of each electrode while increasing the strength against twist force. The electrodes are less likely from breaking in response to an acceleration exerted in a direction perpendicular to the normal detection direction because of reduced weight.Type: GrantFiled: May 5, 1999Date of Patent: November 28, 2000Assignee: Denso CorporationInventors: Minekazu Sakai, Yukihiro Takeuchi, Kazuhiko Kano, Seiji Fujino, Tsuyoshi Fukada, Hiroshige Sugito, Minoru Murata, Hiroshi Muto, Hirofumi Higuchi, Kenichi Ao

Patent number: 5874768Abstract: A high breakdown voltage semiconductor device formed in an SOI structure is disclosed. An MOS transistor composed of a drift layer, p well, a source, a gate, and a drain is formed in an island region surrounded by insulators on a semiconductor substrate. Furthermore, an electricfield-alleviating layer is formed in a bottom portion of the Si island region. The electric-field-alleviating layer is a semiconductor layer of exceeding low concentration, e.g., intrinsic, and therefore a virtual PIN structure is structured among the p well and the drift layer. Because the electric-field-alleviating layer corresponds to an I layer of the PIN structure, a depletion layer is created within the electric-field-alleviating layer when high voltage is applied to the MOS transistor, the high voltage is distributed throughout this depletion layer, and high breakdown voltage can be obtained.Type: GrantFiled: November 7, 1997Date of Patent: February 23, 1999Assignee: Nippondenso Co., Ltd.Inventors: Hitoshi Yamaguchi, Hiroaki Himi, Seiji Fujino

Patent number: 5869872Abstract: A semiconductor integrated circuit device having an SOI structure is capable of preventing occurrence of leak current flowing from a diffusion layer even when a semiconductor element having a pn-junction is included in the semiconductor substrate. The semiconductor integrated circuit device having the SOI structure is formed with a semiconductor layer, or SOI layer, on a p-type semiconductor substrate through a buried insulating film and further with semiconductor circuit elements serving as functional elements at the SOI layer thus formed. As a protection transistor to protect the semiconductor circuit elements, a MOSFET may be formed in which n-type diffusion layers are formed in the semiconductor substrate. The n-type diffusion layers of the MOSFET are to be surrounded by p-type diffusion layers more highly doped than the semiconductor substrate.Type: GrantFiled: November 19, 1997Date of Patent: February 9, 1999Assignee: Nippondenso Co., Ltd.Inventors: Akiyoshi Asai, Jun Sakakibara, Megumi Suzuki, Seiji Fujino
