ABSTRACT:
A bipolar transistor of the multi-emitter type which is provided with a large number of emitter diffusion layers formed in the two-dimensionally arranged state on a base diffusion layer of a substrate, a large number of emitter electrode films formed respectively correspondingly on the emitter diffusion layers, a base electrode film formed on the base diffusion layer, and a collector electrode film formed on the substrate, and the transistor is further provided with a wiring film commonly connected to the large number of emitter electrode films except at least one of the emitter electrode films.
