Abstract
A semiconductor device with high structural reliability and low parasitic capacitance is provided. In one example, the semiconductor device has a surface. The semiconductor device comprises a semiconductor region, wherein an emitter region, a base region, and a collector region are laminated from a side near a substrate of the semiconductor region; an insulating protection layer disposed on the surface; and a wiring layer disposed on the surface, the insulating protection layer forming a via hole from the side of the substrate of the semiconductor region, the via hole being formed to allow the wiring layer to make a contact to an electrode of the emitter region from a side of the substrate where the emitter region, the base region, and the collector region are laminated and where the semiconductor region is isolated.
