Abstract

PURPOSE:To prevent the stoppage of operation of subject device under high collector voltage by a method wherein a gap is provided on the collector region surrounding an emitter layer at the place located between a base electrode lead-out layer and the emitter layer. CONSTITUTION:The N epitaxial layer 3 on a P type Si substrate is isolated by P layer 2 in a frame shape. On the isolated region 3, a P collector layer 4 which is partly overlapping on the P layer 2, P emitter layer 5 surrounded by the layer 4, and an N<+> base electrode lead out layer 6 which is provided in the epitaxial base 3 facing the emitter layer 5 on the outer side of the collector layer are formed. However, on the collector 4 surrounding the emitter 5, a gap 15 is provided between the base electrode lead-out layer 6 and the emitter 5. According to this constitution, depletion layers 7 and 8 leave a tunnel-shape channel by the aid of the gap 15 even at the high voltage VCB existed between collector and base, they do not pinch off at the practically used VCB and an emitter electrode 5a and a base electrode 6a are not disconnected.
