  • Semiconductor device including a metallic conductor for preventing arcing upon failure
    Patent number: 5130784
    Abstract: A semiconductor device includes a metallic electrode formed on a semiconductor substrate, and a metallic terminal formed on a metal base through an insulating material, in parallel to the metal electrode. A metallic wire electrically connects the metallic electrode to the metallic terminal. In a metallic conductor having a current capacity larger than that of the metallic wire, one end is in contact with the metallic terminal, and the other end is in contact with the metallic electrode.
    Type: Grant

  • Radial emitter pressure contact type semiconductor devices
    Patent number: 4035831
    Abstract: The pressure contact type semiconductor device comprises a transistor including a semiconductor substrate, an emitter region having portions protruding from the surface of the substrate and extending in the radial direction from a circle spaced a definite distance from the center of the substrate, a base region surrounding the protruding portions of the emitter region, emitter electrodes provided on respective protruding portions of the emitter region, a collector electrode mounted on the other surface of the substrate, and an electroconductive plate commonly urged against the emitter electrodes.
