Filed: 1988-03-14
Abstract: PURPOSE:To make B-E and B-C junction areas minute by a method wherein a position and a size of an intrinsic base layer or the intrinsic base layer and a collector layer in a transistor are prescribed individually by a wall edge of a taperlike insulating layer formed on a mesa sidewall of an emitter layer. CONSTITUTION:A collector layer 12 is formed on a semiinsulating semiconductor substrate 11; a thick external base layer 17 is laminated on the collector layer; a taperlike insulating layer 15 whose film thickness is increased gradually toward the base layer is provided on mesa sidewalls. In addition, a mesa-shaped emitter layer 14 is formed in such a way that it is filled into the thick external base layer 17; an intrinsic base layer 13 is formed inside the external base layer 17 surrounded by the taperlike insulating layer 15. By this setup, a base- emitter junction capacitance in the intrinsic base region can be reduced without increasing an emitter resistance.
