CONSTITUTION:An Si3N4 film 3 and a poly Si film 4' are superposed on the SiO2 film 2 of an N type Si substrate 1, and B is diffused to the film 4'. After eaves are formed to a photo resist 9 by excessively etching the poly Si 4', an Al film 10 is vapor-deposited in vacuum. The resist 9 is removed, the exposed part of the Si3N4 3 and the SiO2 2 of the lower layer are removed by reactive sputtering, and the Al 10 on the Si3N4 is removed with aqua regia. A poly Si 4 is adhered, and B is diffused from the poly Si 4' to the poly Si 4. At this time, B diffusion gradually stretches from outside the base connecting region of the substrate to the emitter region, the concentration more decreases toward the emitter side, and the thickness becomes thinner. Such a graft base 5 hardly get the generation of the decrease of withstand voltage and the increase of junction capacitance even in contact with the emitter layer. Next, the film 4 is selectively etched with a solution which is difficult to dissolve the poly Si of a high impurity concentration, resulting in the completion.
