摘要:
A method for producing a substrate with black film is provided, comprising forming a dull plating film on a surface of a substrate, forming an electroless plating film containing a sulfur or nitrogen compound on the surface of the plating film, and forming a black film on the surface of the electroless plating film. This substrate with black film is used for devices which generate heat due to sliding or friction or generate/ accumulate heat due to a chemical reaction, such as semiconductor device, vacuum device, rotating device and heat exchanger, and the black film has excellent heat radiating properties with an emissivity of 0.8 or more. Also, this substrate with black film has high corrosion resistance against halogen-type corrosive gases and exhibits excellent release gas properties and corrosion resistance in vacuum devices.

This invention relates to a method for fabricating high performance chip interconnects and packages by providing methods for depositing a conductive material in cavities of a substrate in a more efficient and time saving manner. This is accomplished by selectively removing portions of a seed layer from a top surface of a substrate and then depositing a conductive material in the cavities of the substrate, where portions of the seed layer remains in the cavities. Another method includes forming an oxide layer on the top surface of the substrate such that the conductive material can be deposited in the cavities without the material being formed on the top surface of the substrate. The present invention also discloses methods for forming multi-level interconnects and the corresponding structures.

L'invention a pour objet un procédé formation de siliciure de nickel ou de siliciure de cobalt comprenant les étapes consistant à : - exposer la surface d'un substrat comprenant du silicium avec une solution aqueuse contenant 0.1 mM à 10 mM d'ions or et 0.6 M à 3.0 M d'ions fluor pendant une durée comprise entre 5 secondes et 5 minutes, - déposer par voie electroless sur le substrat activé une couche constituée essentiellement de nickel ou de cobalt, - appliquer un traitement thermique rapide à une température comprise entre 300°C et 750°C, de manière à former le siliciure de nickel ou le siliciure de cobalt. La solution aqueuse contient un agent tensio-actif choisi parmi les composés comprenant au moins un groupement polaire anionique ou non ionique et une chaîne alkyle comprenant de 10 à 16 atomes de carbone. Ce procédé trouve essentiellement application dans la fabrication de mémoires NAND et de cellules photovoltaïques.
摘要:
A zinc-air cell with an anode cup comprising anode active material and a cathode cup comprising catalytic or cathode active material wherein the cathode cup comprises an exposed nickel layer which has been softened to improve electrical contact with the device being powered such as a hearing aid. A cathode cup in desired shape and size is formed of a substrate metal such as cold rolled steel or stainless steel. A nickel layer is plated onto the cathode cup substrate metal and is subsequently heat treated resulting in reduction in the surface hardness of the nickel layer. This improves the reliability of the electrical contact between the cathode cup and the corresponding terminal in the hearing aid or other device being powered.

摘要:
A method is described for plating metal or alloy blanks. The method includes heating the metal or alloy blanks at a recrystallization temperature sufficient to soften the steel for minting; plating the softened metal or alloy blanks with one or more layers of metal or alloy; and heating the plated blanks at a temperature sufficient to reduce plating stresses but below the recrystallization temperature of the outermost plating layer.
