Abstract
PURPOSE: To make possible the formation of a shallow base region and improve high frequency characteristics by forming a polycrystalline Si layer containing an impurity of a specified concentration on the base region in the position away from an an emitter layer, providing a connected base region shadower than the base region right under the emitter layer here, thereafter providing a base electrode on the polycrystalline Si layer.
