Abstract

A bidirectional photothyristor device comprises a semiconductive substrate including an NPNPN quintuple layer in which projections of both the outer layers Ns in the stacking direction are not overlapped so as to define two quadruple layer regions each having either one of the outer layers Ns as an end layer, a pair of main electrodes connecting the two quadruple layer regions in parallel relationship, a recess formed between the two quadruple layer regions within the semiconductive substrate and to which two intermediate P-N junctions are exposed, and means for applying a light trigger signal to the recess.
