Publication number: 20080157380Abstract: Disclosed is a method for forming a metal interconnection in a semiconductor device. In a damascene process, a capping barrier metal layer is formed generally only on a lower metal interconnection in order to prevent the diffusion of atoms from the lower metal interconnection into an upper dielectric layer. The capping barrier metal layer prevents the increase of an effective dielectric constant of a lower inter-metal dielectric layer that surrounds the lower metal interconnection, and may reduce the resistance of the metal interconnection, thereby improving the reliability, speed and/or other characteristics of the semiconductor device.Type: ApplicationFiled: November 23, 2007Publication date: July 3, 2008Inventor: Ji Ho Hong

Publication number: 20080157381Abstract: A semiconductor integrated circuit effectively makes use of wiring channels of wiring formed by a damascene method. When first cells are used, since the M1 power source lines are laid out at positions spaced away from a boundary between the cells, the power source lines are not combined in laying out a semiconductor integrated circuit. As a result, the width of the power source lines is not changed. Accordingly, an interval between the line and a line which is arranged close to the line, determined in response to a line width of the lines, can satisfy a design rule; and, hence, the reduction of the wiring channels can be obviated, whereby the supply rate of the wiring channels can be enhanced, and, further, the integrity of a semiconductor chip can be enhanced.Type: ApplicationFiled: February 29, 2008Publication date: July 3, 2008Inventors: Masayuki OHAYASHI, Takashi Yokoi

Publication number: 20080157408Abstract: A composite hollow aspirator shaft is formed of fiberglass-reinforced phenolic resin that reduces the amount of vibration that is transferred to the motor rotating the shaft, and the motor's bearings. This extends motor and bearing life. When the aspirator tip is rotated in a liquid, fluidic forces are transferred to the shaft. Rather than transmitting those forces into the motor and its bearings, the composite aspirator shaft attenuates the forces to prevent most of them from reaching the motor and its bearings. The composite shaft material has a flexural modulus, or ratio, within the elastic limit of any applied stress, and is sufficiently low to allow the transfer of the flexural or oscillatory energy into heat within the shaft instead of conveying the energy in the form of vibration/oscillations along the axial length of the shaft. As an added advantage, the fiberglass resists abrasion better in wastewater than stainless steel used in the prior art.Type: ApplicationFiled: December 4, 2007Publication date: July 3, 2008Inventors: B.

A computer 50 causes a drive mechanism 48 to separate the pin member 47 from the base 48. Then, the material 80 having adhered to the pin member 47 and the base 48 is drawn out. A projection portion 48b formed of a part of the material 80, which has adhered to the base 48, is formed into a skin needle 81. Consequently, a skin needle can relatively easily be manufactured without requiring excessive time, effort, and cost.Type: ApplicationFiled: December 28, 2005Publication date: July 3, 2008Inventors: Nobuyuki Mukai, Shuken Kuramoto, Tsutomu Takahashi, Yoshinori Oonuma

Publication number: 20080157422Abstract: A composition containing a proton-conductive copolymer, a polymer electrolyte membrane containing the composition; a method of producing the membrane; and a fuel cell employing the membrane. The composition includes: a proton-conductive copolymer comprising a first styrene repeating unit, a second styrene repeating unit, and a dimethylsiloxane repeating unit; and a cross-linked polymer obtained from a cross-linking reaction between a siloxane oligomer having an unsaturated bond and a cross-linking agent. The cross-linked polymer has the same properties as the dimethylsiloxane repeating unit of the proton-conductive copolymer.Type: ApplicationFiled: September 18, 2007Publication date: July 3, 2008Applicant: Samsung SDI Co., Ltd.Inventors: Won-mok Lee, Hae-kyoung Kim, Tae-kyoung Kim

Publication number: 20080157423Abstract: The invention relates to a method for the transverse drawing of an unoriented or longitudinally-oriented film web made from thermoplastic plastic. According to said method, an undrawn or longitudinally-drawn film (9) is introduced into a transverse drawing frame in which heater fields (1) are heated to a transverse drawing temperature TQ, in the attached drawing fields (2) a clip chain is drawn in the transverse direction by divergent (V-shaped) guides and a temperature TF is applied to fixing fields where TQ>TF. In the drawing fields and/or the heating fields (1) the boundary zones (5) of the film (8) are heated or thermally insulated such that the boundary zones (5) of the film (8) have a higher temperature than the middle of the film web (6) on transverse drawing and/or fixing.Type: ApplicationFiled: May 9, 2006Publication date: July 3, 2008Applicant: Treofan Germany GmbH & Co. KGInventors: Leo Wintrich, Robert Hansohn

Publication number: 20080157424Abstract: A process by which many kinds of unstretched films comprising a thermoplastic resin are produced each in a small amount and high yield. A thermoplastic resin (A) to be formed into an unstretched film and another thermoplastic resin (B) are separately melted by heating. The thermoplastic resin (B) is introduced to each edge part of a T-die (2) for extrusion. The two resins are ejected and extruded on a casting roll so that the thermoplastic rosin (B) is disposed on the side of each edge of the thermally melted thermoplastic resin (A). Thus, an unstretched film (20) is formed which comprises the thermoplastic resin (A) and the thermoplastic resin (B) disposed on the side of each edge of the resin (A). Thereafter, the parts constituted of the thermoplastic resin (B) are removed y cutting to form a target unstretched film (20) consisting only of the thermoplastic resin (A).Type: ApplicationFiled: February 25, 2005Publication date: July 3, 2008Applicant: TOYO KOHAN CO., LTD.Inventors: Tadashi Fujii, Takuji Nakamura, Hiroshi Inazawa, Yasuhiro Matsubara

Publication number: 20080157426Abstract: Provided is a method of reducing the incidence of defects caused by die drool or die drips on extruded polymeric products such as films and sheets. The method includes the step of directing a flow of gas towards the die. The flow of gas is substantially parallel to one or more surfaces of the extrudate, and the temperature of the gas is about 50° C. to about 300° C. when it impinges on the surface of the die. Moreover, selecting the temperature or flow rate of the gas provides a method of determining the surface roughness of the extruded polymer.Type: ApplicationFiled: June 7, 2007Publication date: July 3, 2008Inventors: Joseph E. Kotwis, Donald L. Rymer, Christopher J. Nesbitt
