  • Electrode for light-emitting semiconductor devices and method of producing the electrode
    Patent number: 6326223
    Abstract: An electrode for a light-emitting semiconductor device includes a light-permeable electrode formed to come into contact with the surface of the semiconductor, and a wire-bonding electrode that is in electrical contact with the light-permeable electrode and is formed to come into partial contact with the surface of the semiconductor with at least a region in contact with the semiconductor having a higher contact resistance per unit area with respect to the semiconductor than a region of the light-permeable electrode in contact with the semiconductor.
    Type: Grant
    Filed: October 24, 2000
    Date of Patent: December 4, 2001
    Assignee: Showa Denko K.K.
    Inventors: Hisayuki Miki, Takashi Udagawa, Noritaka Muraki, Mineo Okuyama
