Patent number: 8698315Abstract: 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.Type: GrantFiled: August 28, 2012Date of Patent: April 15, 2014Assignee: Kabushiki Kaisha Toyota Chuo KenkyushoInventors: Yoshiyuki Hata, Yutaka Nonomura, Teruhisa Akashi, Hirofumi Funabashi, Motohiro Fujiyoshi, Yoshiteru Omura

Patent number: 7791458Abstract: An alerting illumination device, which includes a detecting component, a danger degree estimating component, a danger assuming component, an illuminating component and a controlling component, is provided. The danger degree estimating component estimates a degree of danger, with respect to a subject vehicle, of the person detected by the detecting component. The danger assuming component, on the basis of the estimated degree of danger, assumes whether or not the person detected by the detecting component is a danger with respect to the subject vehicle. The illuminating component illuminates light. The controlling component, in a case in which the danger assuming component assumes that the person is a danger, controls the illuminating component such that light, which shows a direction of the person who is assumed to be a danger and a distance to the person, is illuminated onto a road surface.Type: GrantFiled: November 13, 2007Date of Patent: September 7, 2010Assignee: Kabushiki Kaisha Toyota Chuo KenkyushoInventors: Keiichi Shimaoka, Kanae Murata, Yuichi Tanaka, Yoshiteru Omura, Isao Aoyagi, Norio Fujitsuka, Hiroyuki Matsubara
