Abstract

PURPOSE:To raise the gate-trigger current, by roughing the surface including the exposed part of a P-N junction formed by providing selectively an N type emitter layer on the upper face side in the P type base layer of a thyristor. CONSTITUTION:The surface is roughed including the exposed part of the upper surface of the P-N junction formed by a P type base layer 3 and an N type emitter layer 4 of a thyristor comprising a P type emitter layer 1, an N type base layer 2, a P type layer 3, an N type emitter layer 4 an anode electrode 11, a cathode electrode 12, and a gate electrode 13. Thus, the carrier lifetime near the surface shortens, and the gate-trigger current is made about several 10muA. Accordingly, it is possible to form a highly sensitive thyristor, which is not liable to malfunction.
