Abstract

PURPOSE:To mitigate current concentration at the time of turn off and to control thermal runaway by providing the second emitter region with a region forming a depletion layer by zero bias and having the same conductive type low impurity density as that of the second emitter region. CONSTITUTION:A first P type emitter layer 11, first N type base layer 12, second P type base layer 13, and second mesa-shaped N type emitter layer 14 are successively stacked. An insulating film 18 covering the exposed part of the P-N junction around the second mesa-shaped emitter layer 14 is provided and electrodes 15, 16, 17 are mounted to form GTO. At that time, an N<-> type layer 19 is provided in the second emitter layer as the same conductive type low impurity region as that of the second emitter layer and current is completely interrupted. In this way, local current concentration generated at the time of turn off is reduced.
