Abstract

PURPOSE:To uniformalize the action of active regions and improve reliability and producibility by a method wherein controlling electrode plates are formed, and the plates and one main electrode plates are unified through insulators. CONSTITUTION:Frame-shaped gate electrode plates 101 are made up which surround an N emitter group 5, the gate electrode plates 101 are unified with cathode electrode plates 10 through insulating films 102 and a gate-cathode unified electrode 100 is built up. The electrode plate 100 is pressure-welded to a base body 1 so that both the gate electrode plates 101 and a gate electrode 7 and both the cathode electrode plates 10 and cathode electrodes 6 contact. Thus, gate signals are equalized even to an active region near to a gate current extracting section 105 at the center of the base body 1 and an active region remote to the section, and the turn-OFF action of each active region is uniformalized.
