  • Electropolishing method
    Patent number: 6783658
    Abstract: A target material is electropolished by applying a voltage between an anode electrode and a counter electrode while bringing the anode electrode into contact with the surface of the target material. The anode electrode is formed of an electrode material having a current density not higher than 10 mA/cm2 upon application of a voltage of +2.5V vs. silver/silver chloride electrode within a 0.1 M perchloric acid solution in an electrochemical measurement using a potentiostat.
    Type: Grant
    Filed: October 2, 2002
    Date of Patent: August 31, 2004
    Assignee: Kabushiki Kaisha Toshiba
    Inventors: Yoshitaka Matsui, Hiroshi Kosukegawa, Masako Kodera, Naoto Miyashita
