Publication number: 20140017821Abstract: An integrated circuit includes four electronic components, a buried UTBOX layer under and plumb with the electronic components, and two pairs of oppositely doped ground planes plumb with corresponding components under the layer. A first isolation trench mutually isolates the ground planes from corresponding wells made plumb and in contact with the ground planes and exhibiting the first doping type. Bias electrodes contact respective wells and ground planes. One pair of electrodes is for connecting to a first bias voltage and the other pair is for connecting to a second bias voltage. Also included are a semiconductor substrate exhibiting the first type of doping and a deeply buried well exhibiting the second type of doping. The deeply buried well contacts the other wells and separates them from the substrate. Finally, a control electrode couples to the deeply buried well.Type: ApplicationFiled: July 1, 2013Publication date: January 16, 2014Inventors: Claire Fenouillet-Beranger, Pascal Fonteneau

Publication number: 20130344626Abstract: A semiconductor substrate having a surface is prepared. An electrical conductor film is formed on a region including the surface of the semiconductor substrate. The step of forming the electrical conductor film includes the steps of measuring, at a point of time when the electrical conductor film is partially formed, a characteristic related to at least one of alternating current loss and alternating current electrical conductivity of the electrical conductor film partially formed, and adjusting a film formation condition for forming the electrical conductor film based on the characteristic. Thereby, a surface roughness of the film being formed can be fed back to the film formation condition.Type: ApplicationFiled: May 14, 2013Publication date: December 26, 2013Applicant: Sumitomo Electric Industries, Ltd.Inventor: Ren Kimura

Patent number: 8604449Abstract: An ion implantation system and method are disclosed in which glitches in voltage are minimized by modifications to the power system of the implanter. These power supply modifications include faster response time, output filtering, improved glitch detection and removal of voltage blanking. By minimizing glitches, it is possible to produce solar cells with acceptable dose uniformity without having to pause the scan each time a voltage glitch is detected. For example, by shortening the duration of a voltage to about 20-40 milliseconds, dose uniformity within about 3% can be maintained.Type: GrantFiled: June 15, 2011Date of Patent: December 10, 2013Assignee: Varian Semiconductor Equipment Associates, Inc.Inventors: Piotr R. Lubicki, Bon-Woong Koo

Patent number: 8580586Abstract: A memory array includes a plurality of memory cells, each of which receives a bit line, a first word line, and a second word line. Each memory cell includes a cell selection circuit, which allows the memory cell to be selected. Each memory cell also includes a two-terminal switching device, which includes first and second conductive terminals in electrical communication with a nanotube article. The memory array also includes a memory operation circuit, which is operably coupled to the bit line, the first word line, and the second word line of each cell. The circuit can select the cell by activating an appropriate line, and can apply appropriate electrical stimuli to an appropriate line to reprogrammably change the relative resistance of the nanotube article between the first and second terminals. The relative resistance corresponds to an informational state of the memory cell.Type: GrantFiled: January 15, 2009Date of Patent: November 12, 2013Assignee: Nantero Inc.Inventors: Claude L.
