  • Patent number: 6871773
    Abstract: The present invention relates to composite metallic ultrafine particles which have excellent dispersion stability and can be produced on an industrial scale, and a process for producing the same, and a method and an apparatus for forming an interconnection with use of the same. A surface of a core metal produced from a metallic salt, a metallic oxide, or a metallic hydroxide and having a particle diameter of 1 to 100 nm is covered with an organic compound including a functional group having chemisorption capability onto the surface of the core metal.
    Type: Grant
    Filed: March 19, 2004
    Date of Patent: March 29, 2005
    Assignee: Ebara Corp.
    Inventors: Akira Fukunaga, Hiroshi Nagasawa, Kaori Kagoshima, Makiko Emoto

  • Patent number: 6638788
    Abstract: A solar cell is manufactured by bringing a front side of a semiconductor crystal substrate into contact with an electrolytic liquid containing a fluoride, placing an electrode in the electrolytic liquid, passing a current between the electrode and the semiconductor crystal substrate and applying light to the semiconductor crystal substrate to generate pairs of holes and electrons. Etching of the substrate proceeds by combining the holes with ions in the front side of the semiconductor crystal substrate which is held in contact with the electrolytic liquid, thereby forming at least one surface irregularity structure thereon.

  • Publication number: 20020102766
    Abstract: A face side of the semiconductor crystal substrate is brought into contact with an electrolytic liquid containing a fluoride, and an electrode is disposed in the electrolytic liquid. A current is produced between the electrode and the semiconductor crystal substrate and applying light to a reverse side of the semiconductor crystal substrate to generate pairs of holes and electrons. The semiconductor crystal substrate is etched by combining the holes with ions in the electrolytic liquid thereby to form a multiplicity of through-holes in the semiconductor crystal substrate.
