Patent number: 7419861Abstract: To form a polycrystalline silicon film having a grain size of 1 ?m or greater by means of laser annealing. A beam emitted from a laser apparatus (101) is split in two by a half mirror. The split beams are processed into linear shapes by cylindrical lenses (102) to (105), and (207), then simultaneously irradiate an irradiation surface (209). If an amorphous silicon film formed on a glass substrate is disposed on the irradiation surface (209), an area will be irradiated by both a linear shape beam entering from a front surface and a linear shape beam that has transmitted through the glass surface. Both linear shape beams irradiate the same area to thereby crystallize the amorphous silicon film.Type: GrantFiled: June 22, 2005Date of Patent: September 2, 2008Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Koichiro Tanaka, Shunpei Yamazaki, Ritsuko Kawasaki

Patent number: 7390714Abstract: Disclosed herein is a method of manufacturing semiconductor devices. The method includes the steps of forming a gate oxide film, a polysilicon film and a nitride film on a semiconductor substrate, and patterning the gate oxide film, the polysilicon film and the nitride film to form poly gates, forming a spacer at the side of the poly gate, forming a sacrifice nitride film on the entire surface, and then forming an interlayer insulation film on the entire surface, polishing the sacrifice nitride film formed on the interlayer insulation film and the poly gates so that the nitride film is exposed, removing top portions of the sacrifice nitride film while removing the nitride film, forming an insulation film spacer at the side exposed through removal of the nitride film, and filling a portion from which the sacrifice oxide film is removed with an insulation film, and forming the tungsten gates in portions from which the nitride films are moved.Type: GrantFiled: December 6, 2005Date of Patent: June 24, 2008Assignee: Hynix Semiconductor Inc.Inventors: Cheol Mo Jeong, Whee Won Cho, Jung Geun Kim

Patent number: 7381628Abstract: A process for producing a tube suitable for microfluidic devices. The process uses first and second wafers, each having a substantially uniform doping level. The first wafer has a first portion into which a channel is etched partially therethrough between second and third portions of the first wafer. The first wafer is then bonded to the second wafer so that a first portion of the second wafer overlies the first portion of the first wafer and encloses the channel to define a passage. The second wafer is then thinned so that the first portion thereof defines a thinned wall of the passage. Second and third portions of the second wafer and part of the second and third portions of the first wafer are then removed, and the thinned wall defined by the second wafer is bonded to a substrate such that the passage projects over a recess in the substrate surface. The second and third portions of the first wafer are then removed to define a tube with a freestanding portion.Type: GrantFiled: February 20, 2006Date of Patent: June 3, 2008Assignee: Integrated Sensing Systems, Inc.Inventors: Douglas Ray Sparks, Nader Najafi

Patent number: 7348200Abstract: The invention provides a method of growing a non-polar a-plane gallium nitride. In the method, first, an r-plane substrate is prepared. Then, a low-temperature nitride-based nucleation layer is deposited on the substrate. Finally, the non-polar a-plane gallium nitride is grown on the nucleation layer. In growing the non-polar a-plane gallium nitride, a gallium source is supplied at a flow rate of about 190 to 390 ?mol/min and the flow rate of a nitrogen source is set to produce a V/III ratio of about 770 to 2310.Type: GrantFiled: March 3, 2006Date of Patent: March 25, 2008Assignees: Samsung Electro-Mechanics Co.
