Abstract
A controlled semiconductor rectifying device, comprising: a semiconductor chip including a base layer of a first type of semiconductivity, a layer of the other type of semiconductivity and a layer of said first type of semiconductivity; a control electrode disposed in said base layer of said semiconductor chip; next to said base layer, a first emitter layer, of said other or second type of semiconductivity; a second emitter layer of said other type of semiconductivity, formed together with said base layer, between said control electrode and said first emitter layer; and a layer of said first type of semiconductivity, formed between the mentioned first and second emitter layers and together with said second emitter layer.
