Abstract

PURPOSE:To enhance the reliability of a semiconductor controlled rectifier by disposing gate lead wires at edge side of a semiconductor substrate outer than gate electrodes, connecting the parts of the wires to parts of the gate electrodes provided between the wires and an nE layer and the other parts of the wires to a pB layer. CONSTITUTION:A gate electrode 11A is formed in flat E shape, a gate lead wire 10 is contacted in low resistance with the central projection M of the gate electrode 11A substantially at the center, and the residual portion thereof is welded to a pB layer 4 at both sides of the central projection M. Since a gate current is thus flown from the wire 10 through the projection M of the electrode 11A to the entire opposite portion of the electrode 11A and to the layer 4, it can reduce the resistance of the layer 4 portion between the wire 10 and the electrode 11A to the ignorable degree.
