Abstract

PURPOSE:To provide a stable performance of gate by a method wherein a side surface of P-N-P-N interconnect structure is covered by an insulation film and a groove passing longitudinally through a junction between N type emitter and P type gate and not reaching down to n type base is provided. CONSTITUTION:At a longitudinal junction between P type gate layer 3 and an implanted N type emitter layer 4 in P-N-P-N quadrant layers structure is made a groove 13 deeper than a surface junction 11 and not reaching to N type base 2 by a chemical etching process. The junction end exposed to the inner surface of the groove is covered by a glass film 14. With this arrangement, a stabilized performance of gate may be assured. Curved portion in P-N junction is removed, some cause for producing variation of performance due to concentrated electric field, SCR having no dispersion in gate performance may easily be obtained.
