Abstract
PURPOSE: To provide a protection diode inside a power transistor in the part between the collector and the base of the transistor as a protection circuit of the power transistor by a simple method.
CONSTITUTION: Low-resistance N+ region 11, high-resistance N- region 12, P region 13 which is formed selectively in region 12 by diffusion and becomes a base region, P+ region 13' which is provided in region 13 for arranging base electrode B subjected to ohmic connection to the base contact, H+ region 14 which is formed by performing selective diffusion in a part of the base region and becomes an emitter region, collector, base and emitter electrodes c, B and E, and N+ region which is formed by performing selective diffusion in a part of P region 13 of the base region are provided, and a diode corresponding to a protection diode is formed by junction to P region 13 of the base region.
