Patent number: 7528049Abstract: A bonded SOI wafer is manufactured by performing bonding in a state where organics exist on a surface of an active layer wafer and/or on a surface of a supporting wafer and performing heat-treating for bonding reinforcement in a state where the organics are trapped at an interface between the active layer wafer and the supporting wafer to form crystal defects at an interface between the active layer wafer and an oxide film and/or at an interface between the supporting wafer and the oxide film. This allows a simple and inexpensive gettering source to be formed at the interface between an SOI layer and an insulating layer (oxide film). Also, the bonded SOI wafer of the present invention that is manufactured by this method can effectively remove heavy-metal impurities that may have a negative impact on the characteristics of the device and/or the withstand voltage characteristics of the oxide film.Type: GrantFiled: July 23, 2007Date of Patent: May 5, 2009Assignee: Sumco CorporationInventors: Yasunobu Ikeda, Shinichi Tomita, Hiroyuki Miyahara

Patent number: 6809933Abstract: First of all, a sub-PCB (6) is fixedly put on a surface of a chassis (5) as shown in an arrow I. At this time, a taper face (9a) of a guide rib (9) guides a fixed position of the sub-PCB (6) in a transverse direction. Next, the sub-PCB (6) is slid forward as shown in an arrow II. A front end of the sub-PCB (6) is led into a taper face (8b) of a fixed click (8) and is guided downward, and gets into the underside of the click and stops in a position of an abutting face (8c).Type: GrantFiled: January 28, 2002Date of Patent: October 26, 2004Assignee: Matsushita Electric Industrial Eo., Ltd.Inventors: Koji Kuchiishi, Toshihiro Higuchi, Hideo Haga, Yasunobu Ikeda

Patent number: 6620285Abstract: A method for bonding substrates to tightly bond two overlaid substrates comprises the steps of: aligning the substrates, freely falling a second substrate onto a first substrate to overlay the first and second substrates; interposing an air layer between the joining surfaces of the first and second substrates, aligning the first and second substrates and holding the aligned first and second substrates; and pressing one point of the aligned two substrates. Thus, the bonded substrates which can be aligned accurately and free from occurrence of voids or the like can be obtained.Type: GrantFiled: October 10, 2001Date of Patent: September 16, 2003Assignee: Sumitomo Metal IndustriesInventors: Shinichi Tomita, Shuhei Tsuda, Yasunobu Ikeda

Patent number: 6515450Abstract: An internal battery (2) has a battery terminal provided on a tip and has a third engagement projection (11) provided on the other end in a vertical direction. A battery housing portion (4) has a connector (5) provided on a tip and has, on a rear end, a battery hook (6) for pressing the third engagement projection (11) interlockingly with a sliding operation from a release position to a lock position. The battery hook (6) is slid from the release position to the lock position to press the third engagement projection (11). Consequently, the battery terminal is caused to abut on the connector (5) and the internal battery 2 is fixed into the battery housing portion (4). A battery (3) is fixed and attachment is thus completed.Type: GrantFiled: February 13, 2002Date of Patent: February 4, 2003Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Takashi Kaiho, Yasunobu Ikeda, Kanta Judai, Takeshi Sato

Patent number: 5636105Abstract: There is disclosed an electronic equipment device. A pair of first and second printed boards are superposed with an electrically-conductive shield frame interposed therebetween in such a manner that those faces of the two printed boards having associated electronic parts mounted thereon are faced to each other. The shield frame has an integral peripheral wall extending over an entire peripheral edge thereof. This peripheral wall surrounds the electronic parts mounted on each of the two printed boards to achieve a shielding effect. Right and left sides of the stack of the two printed boards and the shield frame interposed therebetween are clamped respectively by a pair of resilient clamping members of a U-shaped cross-section to thereby provide a unitary assembly. These resilient clamping members cause earth portions of the first and second printed boards to be electrically connected to the shield frame.Type: GrantFiled: July 18, 1995Date of Patent: June 3, 1997Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Youji Inomata, Yasunobu Ikeda, Michiyoshi Kudoh, Kanta Judai
