  • Publication number: 20120164328
    Abstract: A substrate is transferred to a processing container, and a film formation raw material containing cobalt amidinate and a reducing agent containing a carbonic acid in a vapor phase are introduced into the processing container, thereby a Co film is formed on the substrate.
    Type: Application

  • Publication number: 20120064708
    Abstract: In a method for forming a stacked substrate of a MOS (Metal Oxide Semiconductor) structure including an oxide film serving as a gate insulating film formed on a semiconductor material layer having a film or substrate shape; and a conductive film serving as a gate electrode formed on the oxide film, a polysilane film on the semiconductor material layer is formed by coating a polysilane solution on a surface of a substrate to which the semiconductor material layer is exposed. A film containing metal ions is formed on the polysilane film by coating a metal salt solution thereon, and the polysilane film and the film containing metal ions are respectively modified into a polysiloxane film and a film containing fine metal particles to form the stacked substrate.

  • Publication number: 20110174630
    Abstract: A film formation method includes preparing a substrate formed a Co film as a seed layer on a surface of the substrate, applying a negative voltage to the substrate such that a surface potential of Co is lower than an oxidation potential of the Co, and in a state when the negative voltage is applied to the substrate, dipping the Co film in a plating solution mainly containing copper sulfate solution, thereby a Cu film is formed on the Co film of the substrate by electroplating.
