Abstract
PURPOSE:To decrease the resistance values of electrodes and to implement a high speed in circuit operation, by forming a metal layer or a metal alloy layer on the surface of at least lower electrodes other than the overlapped part of the lower electrodes and an upper electrode, which comprise a semiconductor material. CONSTITUTION:Platinum is deposited on a silicon substrate 101, which include base and emitter lead-out electrodes 106 and 107. Thereafter, heat treatment is performed. A platinum silicide layer 111 is formed on the surfaces of the base and emitter lead-out electrodes 106 and 107. Then, a silicon oxide film 109 is deposited on the entire surface. A hole is provided in said film. An aluminum electrode 110 is formed. Therefore, the most part of the base lead-out electrode 106, which is connected to an outer base 103, is covered with the low resistance platinum silicide layer 111. Thus the resistances of the lead-out electrodes can be made low, and the speed of the circuit operation can be made fast.
