ABSTRACT:
Disclosed is a discrete semiconductor device comprising a Si body having an emitter region, a base region and a collector region, an SiO.sub.2 layer disposed on the surface of the body, a polyimide resin having a thickness of 5 .mu. disposed on the SiO.sub.2 layer, electrodes penetrating through the SiO.sub.2 layer and the polyimide resin thereby contacting the emitter region and the base region, respectively and extending on the surface of the polyimide resin, whereby it becomes easy to bond a wire connected to an external electrode with the electrodes.
