Patent number: 7727831Abstract: The leakage current generated due to the extension of the depleted layer to the end of the chip is reduced. In MOSFET 100, the depths of the trenches 112 in the gate pad portion 50 and the circumference portion 70 are larger than the depths of the trenches 111 in the cell region 60. Therefore, the depleted layer extending from the cell region 60 along the direction toward the gate pad portion 50 or the direction toward the circumference portion 70 is blocked by the presence of the trench 112. In other words, an extending of the depleted layer can be terminated by disposing the trench 112, so as to avoid reaching the depleted layer to the end of the semiconductor chip. Accordingly, a leakage current generated from the cell region 60 along the direction toward the end of the semiconductor chip can be reduced.Type: GrantFiled: September 20, 2005Date of Patent: June 1, 2010Assignee: NEC Electronics CorporationInventor: Kinya Ohtani

The portion includes the leading outer edge region of the wafer. The area of the wafer portion is significantly less than the total surface area of the planar wafer surface. Power density is minimized. As a result, bubbles are removed from the wafer surface and cavitation in the liquid bath is avoided. In some embodiments, the liquid bath is de-gassed to inhibit bubble formation.Type: GrantFiled: September 29, 2008Date of Patent: June 1, 2010Assignee: Novellus Systems, Inc.Inventors: Bryan L. Buckalew, Jonathan D. Reid, Johanes H. Sukamto, Frederick Dean Wilmot, Richard S. Hill

Patent number: 7727864Abstract: Metallic-compound films are formed by plasma-enhanced atomic layer deposition (PEALD). According to preferred methods, film or thin film composition is controlled by selecting plasma parameters to tune the oxidation state of a metal (or plurality of metals) in the film. In some embodiments, plasma parameters are selected to achieve metal-rich metallic-compound films. The metallic-compound films can be components of gate stacks, such as gate electrodes. Plasma parameters can be selected to achieve a gate stack with a predetermined work function.Type: GrantFiled: November 1, 2006Date of Patent: June 1, 2010Assignee: ASM America, Inc.Inventor: Kai-Erik Elers

Patent number: 7727866Abstract: The manufacture of solar cells is simplified and cost reduced through by performing successive ion implants, without an intervening thermal cycle. In addition to reducing process time, the use of chained ion implantations may also improve the performance of the solar cell. In another embodiment, two different species are successively implanted without breaking vacuum. In another embodiment, the substrate is implanted, then flipped such that it can be and implanted on both sides before being annealed. In yet another embodiment, one or more different masks are applied and successive implantations are performed without breaking the vacuum condition, thereby reducing the process time.Type: GrantFiled: March 4, 2009Date of Patent: June 1, 2010Assignee: Varian Semiconductor Equipment Associates, Inc.Inventors: Nicholas Bateman, Atul Gupta, Paul Sullivan, Paul Murphy
