Publication number: 20050023644Abstract: In the manufacturing process of a Bi-CMOS semiconductor device, which includes a CMOSFET and a bipolar transistor, the steps for forming a well region, source regions, and drain regions of the CMOSFET are also used for forming the bipolar transistor. One of the steps is used for introducing impurities of the same conductivity type in a surface of a base region of the bipolar transistor in order to form a high impurity concentration region in the surface. The high impurity concentration region is formed such that the distance between an emitter region of the bipolar transistor and the high impurity concentration region becomes 1 to 2 ?m. The shift in device characteristics of the bipolar transistor is improved by the high impurity concentration region even if the impurity concentration is relatively low at the surface of the base region of the bipolar transistor.Type: ApplicationFiled: August 31, 2004Publication date: February 3, 2005Inventors: Takuya Okuno, Shoji Mizuno, Toshitaka Kanemaru

Patent number: 6578372Abstract: A variable displacement compressor has a control valve for controlling the displacement of the compressor. When the pressure in a discharge chamber of the compressor (discharge pressure) is equal to or higher than a first threshold value, a controller sets a duty ratio, which is sent to the control valve, to zero % to limit the discharge pressure. As a result, the compressor displacement is minimized and the discharge pressure is lowered. Therefore, the pipes of an external refrigerant circuit does not receive excessive load based on high discharge pressure. When the displacement of the compressor is minimized, circulation of refrigerant in the refrigerant circuit is stopped and refrigerant containing lubricant circulates within the compressor.Type: GrantFiled: November 9, 2001Date of Patent: June 17, 2003Assignee: Kabushiki Kaisha Toyota JidoshokkiInventors: Tetsuhiko Fukanuma, Hiroshi Kubo, Takuya Okuno

Patent number: 6420281Abstract: One or more capacitors are formed using thermally oxidized films formed on a silicon layer of an SOI substrate. The capacitors may be formed alone or together with other semiconductor elements on a single SOI substrate. A diffuse layer having an impurity in a high density is first formed on the silicon layer, and then an oxidized film is formed on the diffused layer by thermal oxidation. Then, contaminants in the oxidized film are driven-out under a high temperature heat treatment, thereby to improve quality of the oxidized film, such as durability against a high voltage. Plural capacitors may be formed using oxidized films having a respectively different thickness, by repeating thermal oxidation and removal of the oxidized film.Type: GrantFiled: December 6, 2000Date of Patent: July 16, 2002Assignee: Denso CorporationInventors: Takuya Okuno, Akira Yamada, Yoshiaki Nakayama
