IPC: H01L21/8222
Filed: 1988-03-24
Abstract: PURPOSE:To reduce base-emitter capacitance by obliquely implanting ions in the side face of an emitter-mesa and forming a high resistance layer on the side face of the emitter-mesa in a taper shape so that a base-emitter joint surface is made narrower than an emitter-electrode forming surface as an uppermost layer. CONSTITUTION:An emitter-mesa 46 for a transistor is shaped by forming a tapered high resistance layer 8 onto the side faces of the emitter-mesa 46 so that a base-emitter joint surface is made narrower than an emitter-electrode 45 forming surface as an uppermost section. The high resistance layer 8 can easily be shaped by obliquely implanting ions to the side faces of the emitter- mesa 46 by utilizing a mask for forming the emitter-mesa. Consequently, the width length L1 of the base-emitter joint surface is set at a value narrower than that L2 of the emitter-electrode forming surface by the tapered high resistance layer 8. Accordingly, base-emitter capacitance is reduced without increasing emitter resistance.
