  • Semi-conductor device capable of supporting high amperages of inverse current
    Patent number: 4019195
    Abstract: The present invention relates to a surge arrester or transient voltage clipper device comprising a quasi-monocrystalline semiconductor (silicon for instance), with an extra large etch pit density or low-angle boundary grains. At these dislocation lines the dopant is present in a larger concentration, and multiple p.sup.+-n.sup.+ junctions are formed preferentially at these grain boundaries as an external impurity of the opposite type to the background dopant is diffused preferentially through these dislocation lines.
