Title: Semiconductor device
Inventor: NAKASAKI YASUTAKA
IPC: H01L29/72
Filed: 1988-06-27
Abstract: PURPOSE:To reduce a base resistance and improve the performance of a transistor as a whole by a method wherein a metal silicide layer which is partially brought into contact with a base region and an emitter electrode are separated from each other by using a side wall insulating film partially. CONSTITUTION:A metal silicide layer 110 formed on a base 109 and a wiring 111 made of semiconductor material are separated from each other with an insulating film 106 and a side wall insulating film 107. After an aperture for an emitter part is drilled in the insulating film 106 formed on the metal silicide layer 110, a resistance film is formed over the whole surface and subjected to whole surface etching to form the side wall insulating film. With this constitution, as the resistance of the metal silicide layer 110 is normally significantly low compared with the impurity diffusion resistance, the base resistance can be significantly reduced. Further, as a distance between the metal silicide layer 110 and an emitter 108 can be substantially shortened, the base resistance can be further reduced.
