  • Patent number: 4822633
    Abstract: A method of plating a pattern of metal (e.g. copper or nickel) on a dielectric surface, i.e. surface of a dielectric material such as a synthetic resin or ceramic. The method comprises the preliminary step of masklessly treating the dielectric surface to selectively activate preselected areas thereof so that the dielectric surface in contact with a priming solution becomes catalytic, and thereby receptive to electroless metal deposition, selectively at those areas. The treated dielectric surface is contacted with an electroless plating solution to allow metal therefrom to auto-reductively deposit selectively at those catalized areas, thereby forming the pattern of metal desired on the dielectric surface.

  • Patent number: 4775547
    Abstract: The preparation of multilayer filament reinforced consolidated articles is found to be possible because of the unique properties of RF plasma sprayed deposits. Pursuant to this method, a first layer of plasma deposited foil is made with a rough upper surface. A layer of closely spaced aligned reinforcing filaments is positioned on the rough surface. A second foil of RF plasma deposited metal is formed in and on the layer of filaments. A second layer of filaments is positioned on the second foil and a third foil is formed in and on the second layer. The three foils are integrated because of the strong tendency of the RF plasma sprayed metal to penetrate through, wet the fibers, and bond to the layer underneath.

  • Patent number: 4766006
    Abstract: The invention relates to a process for the low pressure chemical vapor deposition (LPCVD) of metal silicide, especially molybdenum silicide, on a substrate at a low temperature. The walls of a LPCVD reactor which contains a heated pedestal for holding a substrate are cooled and the pedestal is heated so the substrate temperature reaches a desired level, depending on the metal silicide to be deposited. A metal halide and a silane or disilane are fed separately into the deposition chamber and mixed behind a small baffle plate at the entrance. The metal silicide is deposited on the substrate surface. It is preferred that the substrate be pre-treated with H.sub.2 plasma before deposition.

  • Patent number: 4766009
    Abstract: A selective working method in which the surface to be worked of a workpiece is locally irradiated with energy beams and an electroless plating solution or an electroless etching solution is contacted with the irradiated workpiece surface, with the electroless plating solution or the electroless etching solution flowing continuously in the substantially same direction of as the direction of an irradiation of energy beams. The electroless plating of the electroless etching can be conducted selectively by this method. Above selective working method is best suited for the formation or correction (repair, filling up etc.) of micro-patterns on the workpiece such as metals, semi-conductors, insulators, etc.

  • Patent number: 4762732
    Abstract: The invention provides a process for forming an electrical conductor pattern on desired areas of a substrate comprising the steps of applying a predetermined pattern of silver polymer ink on the substrate and at least partially curing it. A layer of silver solder paste is then applied over the cured polymer ink to a width larger than that of the ink. The solder paste is then reflowed and allowed to solidify, whereby the silver polymer ink becomes encapsulated in the reflowed silver solder to form the desired pattern of conductors which may then be covered with a layer of dielectric material comprising a cured non-conductive polymer ink.
