Abstract

PURPOSE: To simplify wrok, and to reduce the cost of materials by forming an internal electrode body, touching a semiconductor element constituting a thyristor, of a copper plate and copper rod.
CONSTITUTION: Plunger-type internal electrode body 2 is made in contact with semiconductor element 1 which has an anode electrode on its lower surface, a center gate electrode at the center of its upper surface, and a cathode electrode surrounding it. Namely, one flank of this internal electrode body 2 is pressure-welded to the cathode electrode, and the other flank is connected to the cathode electrode terminal while a lead wire for leading out a center gate electrode is inserted into the through hole provided to the flank of the rod part extending from the plane part along its axis. Internal electrode body 2 in this constitution is formed as follows: copper plate 22m is press-worked to obtain disc 22a with through hole 22b at its center, to which plunger-type copper rod 22c provided with notch-worked part 22d penetrating from the center to the flank at one terminal is welded, thereby obtaining internal electrode body 22.
