Publication number: 20030205324Abstract: A wafer holder comprises a circular, disc-shaped main portion and a rib extending generally downward from a lower surface of the main portion. The rib encircles the vertical center axis of the wafer holder. The upper surface of the main portion has a wafer-receiving pocket defined by an inner pocket surface surrounded by an outer shoulder. The rib is closed to completely surround a vertical center axis of the main portion. The rib helps to prevent the main portion from inducing symmetric concavity during the manufacture of the wafer holder. In other words, the rib helps to maintain the flatness of the upper surface of the outer shoulder while the main portion is made symmetrically concave.Type: ApplicationFiled: May 3, 2002Publication date: November 6, 2003Inventors: Tony J.

Publication number: 20030203111Abstract: A method for chemical vapor deposition of copper metal thin film on a substrate includes heating a substrate onto which the copper metal thin film is to be deposited in a chemical vapor deposition chamber; vaporizing a precursor containing the copper metal, wherein the precursor is a compound of (&agr;-methylstyrene)Cu(I)(hfac), where hfac is hexafluoroacetylacetonate, and (hfac)Cu(I)L, where L is an alkene; introducing the vaporized precursor into the chemical vapor deposition chamber adjacent the heated substrate; and condensing the vaporized precursor onto the substrate thereby depositing copper metal onto the substrate. A copper metal precursor for use in the chemical vapor deposition of a copper metal thin film is a compound of (&agr;-methylstyrene)Cu(I)(hfac), where hfac is hexafluoroacetylacetonate, and (hfac)Cu(I)L, where L is an alkene taken from the group of alkenes consisting of 1-pentene, 1-hexene and trimethylvinylsilane.Type: ApplicationFiled: June 2, 2003Publication date: October 30, 2003Inventors: Wei-Wei Zhuang, Lawrence J. Charneski, David R. Evans, Sheng Teng Hsu

Patent number: 6638572Abstract: A particulate silicone based material and method for forming a heat resistant composite is provided. The particulate silicone based material is heated to a temperature between about 200° F. and about 400° F. The particulate silicone based material is cooled until a solid composite is formed. The solid composite is resistant to melting and thermal decomposition when heated to temperatures of at least 3000° F. The particulate silicone based material may be formed by mixing liquid silicone resin with a catalyst and powdered silicone molding compound.Type: GrantFiled: June 27, 2001Date of Patent: October 28, 2003Inventor: Charles F. Inglefield

Patent number: 6627261Abstract: The present invention relates to a method and apparatus for coating a moving paper web (2), in which method the web (2) to be coated is passed to a coater station and the coating is applied to at least one surface of the moving web (2) by means of spraying nozzles (1) disposed in the interior of an enclosing hood (9). The web (2) is supported noncontactingly by means of air jets directed toward at least one side of the web (2).Type: GrantFiled: August 2, 2001Date of Patent: September 30, 2003Assignee: Metso Paper, Inc.Inventors: Mika Vähäkuopus, Vilho Nissinen, Seppo Luomi

Publication number: 20030180581Abstract: The present invention relates to a method of growing a ZnO film using chemical vapour deposition (CVD), and to a ZnO film grown according to the method. The method comprises the steps of: a) providing a precursor in vapour form, the precursor substantially comprising Zn4O(O2CNRARB)6, where RA and RB are any combination of alkyl or perfluoralkyl groups; b) decomposing at least some of the vapour at the surface of the substrate such that the film of zinc oxide forms. An advantage of using this precursor material is that, unlike in the prior art, no deliberate introduction of water vapour to improve chrystalographic orientation is required. Higher purities in oxide films are produced.Type: ApplicationFiled: April 9, 2003Publication date: September 25, 2003Inventors: Antonella Julie Petrella, Robert Norman Lamb, Nicholas Kenneth Roberts
