Abstract:
A method of manufacturing a semiconductor device, comprising the steps of:forming a collector layer of a first conductivity type having a main surface;forming a base layer of a second conductivity type in a prescribed region on the main surface of said collector layer;forming an emitter layer in a prescribed region on the main surface of said base layer;forming a first insulating layer having an opening on said emitter layer at least in a prescribed region on said base layer;forming a semiconductor layer on said first insulating layer;forming a second insulating layer on an upper surface and a side surface of said semiconductor layer; andforming an emitter electrode so as to be electrically connected to said emitter layer within the opening of said first insulating layer, and to extend on and along a surface of said second insulating layer.
