ABSTRACT:
The disclosed thyristor comprises an n.sup.- semi-conductor layer, a p.sup.- semiconductor layer disposed on one surface of the n.sup.- layer to form a pn junction between them, an n.sup.+ and a p.sup.+ semiconductor layer disposed on the other surfaces of the n.sup.- and p.sup.- layers respectively to serve as main electrodes and a p.sup.+ and a n.sup.+ apertured gate layers disposed within the n.sup.- and p.sup.- layers respectively and provided with a gate electrode. An intrinsic semiconductor layer may be substituted for the n.sup.- and p.sup.- layers. A process of producing such a thyristor is also disclosed.
