Abstract:
In the film deposition method of the present invention, an organometallic fluid, which has an organic metal such as a copper diketonate as its main component, and which precipitates film deposition material through a pyrolytic decomposed reaction, is first prepared; and the organometallic fluid is then applied onto a semiconductor wafer at a certain temperature within the non-reactive range of the organic metal. Afterwards, the wafer is heated to a predetermined temperature, the organic metal within the organometallic fluid that is applied onto the wafer is pyrolytically decomposed, and film is formed on the wafer. With this method, since application is performed at a temperature within the non-reactive range of the organic metal, deposition of the film does not occur, allowing uniform and homogenous application to be performed. Also, since pyrolytic decomposition is performed separately in a later process, a stable reaction may be assured, so that a film of uniform thickness and quality may be deposited.
Abstract:
A method of applying a layer of exogenous inorganic oxide to a metal article which method involves heating a coating of a coupling agent for a temperature and for a time sufficient to convert the coating to a layer of exogenous inorganic oxide. Also a method of adhering a metal article to an adhesive and/or a composite and a method of adhering a metal article to a substrate.
Abstract:
The disclosure relates to a metal oxide film formed on a glass substrate by the so-gel process with using a solution of a metal alkoxide. To afford water repellency to the oxide film, a fluoroalkylsilane is mixed with an alkoxysilane solution in the molar ratio of the alkoxysilane to the fluoroalkylsilane ranging from 1:10 to 10:1. Then, the mixed solution is diluted with a solvent such that the total concentration of the alkoxysilane and the fluoroalkylsilane is from 1 to 10 wt % in a diluted solution. Then, water in the amount of 100 mol % to 1000 mol % of the total amounts of the fluoroalkylsilane and the alkoxysilane is added to the diluted solution so as to partially hydrolyze the fluoroalkylsilane and the alkoxysilane, thereby forming a sol. Then, the sol is applied to the glass substrate, and the coated glass substrate is heated so as to form the metal oxide film thereon.
Abstract:
A thin film forming apparatus which forms a thin film over the film forming surface of a substrate by spraying a mist of a source solution produced by atomization over the film forming surface of the substrate heated to a given temperature. The substrate conveying direction is reversible, or a nozzle for spouting the mist into a film forming chamber and an exhaust duct are connected removably to a hearth forming the bottom wall of the film forming chamber and can be switched with one another. The film forming apparatus is capable of forming thin films of different laminate constructions.

Abstract:
A PROCESS FOR PRODUCING A SURFACE-TREATED STEEL PLATE HIGH IN THE ANTICORROSIVENESS, PARTICULARLY ADAPTED AS A MATERIAL FOR MAKING CANS, ON THE PRINCIPLE OF THE THERMODECOMPOSING PLATING, WHEREIN THE STEEL PLATE IS COATED WITH AN AQUEOUS SOLUTION CONTAINING NITRATE AND/OR ACETATE OF NI AS THE MAIN COMPONENT THEREOF AND OF OTHER METALS SUCH AS CR, MN, ZN AND AL AS SELECTIVE COMPONENTS AND THEN HEATED AT A CERTAIN RANGE OF TEMPERATURE SO AS TO CAUSE THE THERMODECOMPOSING REACTION TO CAUSE THEREBY A STRONG FILM CONTAINING METALLIC NICKEL AND AT LEAST ONE METAL OXIDE TO FORM ON THE SURFACE OF THE STEEL PLATE.
Abstract:
THIS NVENTION RELATES TO A PROCESS OF FORMING A METALLIC COPPER LAYER OF A UNIFORM THICKNESS ON THE SURFACE OF WORKPIECE MADE OF ALUMINUM OR ALUMINUM BASE ALLOY BY APPLYING FINELY DIVIDED COPPER HALIDE PARTICLES ON SAID SURFACE UNIFORMLY WITH AID OF A HIGHER ALIPHTIC MONOHYDRIC ALCOHOL CONTAINING 6-12 CARBON ATOMS OR A CYCLOALIPHATIC MONO-HYDRIC ALCOHOL CONTAINING 6-8 CARBON ATOMS AS THE ADHESIVE MEDIUM, AND THEN HEATING SAID SURFACE TO A SUFFICIENT TEMPERATURE TO REACT THE COPPER HALIDE WITH THE ALUMINUM MATERIAL OF THE WORKPIECE AT THE SURFACE OF THE WORKPIECE, WHEREBY METALLIC COPPER IS LIBERATED, DEPOSITED ON AND PARTLY DIFFUSED INTO THE SURFACE OF THE WORKPIECE AND A FIRMLY ADHERED COPPER LAYER OF A UNIFORM THICKNESS MAY BE FORMED ON THE SURFACE OF THE ALUMINUM OR ALUMINUM BASE ALLOY MATERIAL AND, IF DESIRED, WITHIN A SHARPLY LIMITED AREA OF THE SURFACE OF THE WORKPIECE.
Abstract:
A process for depositing a metallic aluminum film on a substrate material which comprises: depositing a transition metal catalyst on said substrate; depositing an aluminum hydride compound on said substrate in contact with said catalyst; contacting said treated substrate in a heated bath consisting of an inert liquid, thereby decomposing said aluminum hydride material and providing a metallic aluminum coating on said substrate; removing said aluminum coated substrate from said bath and removing said inert liquid to provide said metallic aluminum coating on the substrate.
