    摘要: In a bipolar transistor block, a base layer (20a) of SiGe single crystals and an emitter layer (26) of almost 100% of Si single crystals are stacked in this order over a collector diffused layer (9). Over both edges of the base layer (20a), a base undercoat insulating film (5a) and base extended electrodes (22) made of polysilicon are provided. The base layer (20a) has a peripheral portion with a thickness equal to that of the base undercoat insulating film (5a) and a center portion thicker than the peripheral portion. The base undercoat insulating film (5a) and gate insulating films (5b and 5c) for a CMOS block are made of the same oxide film. A stress resulting from a difference in thermal expansion coefficient between the SiGe layer as the base layer and the base undercoat insulating film 5a can be reduced, and a highly reliable BiCMOS device is realized.

    摘要: In the method for fabricating a semiconductor device of the present invention, a collector layer of a first conductivity type is formed in a region of a semiconductor substrate sandwiched by device isolation. A collector opening is formed through a first insulating layer deposited on the semiconductor substrate so that the range of the collector opening covers the collector layer and part of the device isolation. A semiconductor layer of a second conductivity type as an external base is formed on a portion of the semiconductor substrate located inside the collector opening, while junction leak prevention layers of the same conductivity type as the external base are formed in the semiconductor substrate. Thus, the active region is narrower than the collector opening reducing the transistor area, while minimizing junction leak.
