  • Semiconductor device with built-up low resistance contact
    Patent number: 4505029
    Abstract: A semiconductor device having particularly low resistance connection to a portion thereof carrying substantial current is described. First and second electrodes are provided on a major surface of the semiconductor, the first electrode providing lateral contact to a control region of the semiconductor device; the second electrode providing low impedance vertical contact to the high current carrying region. A conductive plate is supported between upstanding spaced apart portions of the second electrode and is thereby vertically spaced apart from the first electrode.
