Patent number: 7497963Abstract: In this etching method, since an etching gas is introduced before introduction of free radicals into a processing chamber, the etching gas has been adsorbed on the surface of substrates when the free radicals are introduced. Accordingly, the free radicals react with the etching gas adsorbed on the surface of the substrates, and the reaction proceeds uniformly on the surface of the substrate. As a result, nonuniform etching does not occur on the surface of the substrate. Moreover, since the reaction between the etching gas and the free radicals occurs on the surface of the substrate, an intermediate product produced according to the reaction between the etching gas and the free radicals reacts with an etching object promptly. Therefore, the intermediate product is not exhausted from the processing chamber 12 excessively, and hence the etching efficiency is high.Type: GrantFiled: January 10, 2005Date of Patent: March 3, 2009Assignees: Samsung Electronics Co., Ltd., ULVAC, Inc.Inventors: Kwang-Myung Lee, Ki-Young Yun, Seung-Ki Chae, No-Hyun Huh, Wan-Goo Hwang, Jung-Hyun Hwang, Shinji Yanagisawa, Kengo Tsutsumi, Seiichi Takahashi

Publication number: 20090053425Abstract: A method for producing single-dimensioned gold-nano-particle patterns having a single-particle resolution in which the line-width is only limited by the particle size. Initially, a focused electron beam is used to generate a positive charge layer on an SiO2 surface. Biotinated DNA molecules attracted by these positive charges are then used to acquire Au-nano-particles revealing the e-beam exposure patterns. The particles in the single-line patterns become separated in an orderly manner, due to the repulsive force between different Au colloidal particles. Each single-line pattern has potential use in nano-photonics and nano-electronics. In nano-electronics, the line patterns serve as a template for high or low resistance conductive nano-wires. Low resistance wires exhibit linear current-voltage characteristics with an extremely high maximum allowed current density. The high resistance wires display charging effect with clear Coulomb oscillation behavior at low temperatures.Type: ApplicationFiled: August 21, 2007Publication date: February 26, 2009Applicant: Academia SinicaInventors: Chii-Dong Chen, Hung-Yi Lin, Li-Chu Tsai

Publication number: 20080106842Abstract: A mounting device includes a mounting body for sustaining a target object to be processed thereon; an electrostatic chuck disposed on the mounting body and having an electrode layer interposed between insulating layers, and the electrostatic chuck serving to electrostatically attract and hold the target object on a surface of the insulating layer by a electrostatic force generated between the electrode layer and the target object by a voltage applied to the electrode layer. Herein, an electrostatic chuck layer, which is one of the insulating layers on the side of a top surface of the electrode layer, is made of a plasma spray coating of yttrium oxide, which is formed by a plasma spraying, having a thickness of about 200 ?m to 280 ?m, and the electrostatic chuck layer has a surface roughness dependent on a particle diameter of the yttrium oxide used in the plasma spraying.Type: ApplicationFiled: November 2, 2007Publication date: May 8, 2008Applicant: TOKYO ELECTRON LIMITEDInventors: Hiroharu ITO, Kenichi Kato, Takehiro Ueda

Patent number: 7368151Abstract: An antiscattering grid for an X-ray imaging apparatus of the type comprising a substrate having a plurality of metallized partitions that together define a plurality of cells distributed over the substrate. The partitions allow passage of the X-rays emitted from a source lying in line with the grid, and absorbing the X-rays not coming directly from this source. The substrate is made of a polymer material that may be formed by radiation curing of a monomer sensitive to this radiation. The substrate may be substantially planar and the partitions may be oriented to form a focused grid.Type: GrantFiled: October 11, 2002Date of Patent: May 6, 2008Assignee: GE Medical Systems Global Technology Company, LLCInventors: Henri Souchay, Remy Klausz, Guillaume Bacher, Bruno Gilles Richou

Publication number: 20080057219Abstract: A substrate treating apparatus includes a substrate support unit with a chuck on which a substrate is loaded; a bottom chamber having an open top and configured to surround the circumference of the chuck; a top chamber configured to open or close the top of the bottom chamber such that the substrate is dried while the top chamber is sealed from the outside; and a direct injection nozzle member installed at the top chamber to inject fluid directly to the substrate while the top of the bottom chamber is closed. According to the substrate treating apparatus, drying efficiency of an entire substrate is enhanced, external contaminants are blocked, and generation of an oxide layer is suppressed.Type: ApplicationFiled: May 31, 2007Publication date: March 6, 2008Inventors: Hyun-Jong Kim, Kyo-Woog Koo, Jung Keun Cho

Patent number: 7309515Abstract: The present invention is related to a method for fabricating an imprint mold which can be used in the field of nano-imprint lithography. Firstly, a diamond film and a photoresist film are successively formed onto a substrate; wherein the photoresist film is more capable of anticorrosion than the diamond film. Then an energy beam lithography system is provided to make the photoresist film form a photoresist mask with particularly arranged patterns. Because of the etching selectivity between the diamond film and the photoresist film, on the surface of the diamond film a pattern can be easily formed with recessions and protrusions according to the photoresist mask by dry etching method.Type: GrantFiled: February 4, 2004Date of Patent: December 18, 2007Assignee: Industrial Technology Research InstituteInventors: Hung-Yin Tsai, Chih-Hung Wu, Chih-Yung Cheng

Patent number: 7300684Abstract: The coating of internal surfaces of a workpiece is achieved by connecting a bias voltage such that the workpiece functions as a cathode and by connecting an anode at each opening of the workpiece. A source gas is introduced at an entrance opening, while a vacuum source is connected at an exit opening. Pressure within the workpiece is monitored and the resulting pressure information is used for maintaining a condition that exhibits the hollow cathode effect. Optionally, a pre-cleaning may be provided by introducing a hydrocarbon mixture and applying a negative bias to the workpiece, so as to sputter contaminants from the workpiece using argon gas. Argon gas may also be introduced during the coating processing to re-sputter the coating, thereby improving uniformity along the length of the workpiece. The coating may be a diamond-like carbon material having properties which are determined by controlling ion bombardment energy.Type: GrantFiled: July 15, 2004Date of Patent: November 27, 2007Assignee: Sub-One Technology, Inc.Inventors: William John Boardman, Andrew William Tudhope, Raul Donate Mercado
