发明名称 SEMICONDUCTOR DEVICE FOR PROTECTION OF OVERVOLTAGE
摘要 PURPOSE:A high impurity concentration region of the same conductivity type as a substrate is formed across the substrate immediate beneath gate controlling electrode and a region of opposite conductivity type formed on this substrate, whereby breakdown voltage in the reverse direction is diminished and surge voltage resistance is improved.
