    Abstract: The method of fabricating bipolar transistor comprises the steps of forming an N-type polysilicon and nitride pattern on an active region, forming a sidewall on the sides of the pattern, selectively growing epitaxial layer between the sidewall and the field oxide, highly doping the epitaxial layer with P-type, performing heat treatment to the polysilicon layer and highly doped epitaxial layer to form emitter and base region, depositing a metal and then heat treating it to form salicide layer, and selectively removing the salicide layer. The method simplifies formation of electrode and improves the transistor performance.

    Abstract: The method manufactures a BiCMOS device having a bipolar transistor of which emitter and base are self aligned. The intrinsic base of a vertical type PNP transistor is formed by using an n+ polysilicon layer as a mask and the extrinsic base of a vertical type PNP transistor is formed by using the n+ polysilicon as a diffusion source. The self-aligned emitter of a vertical type PNP transistor is formed by using a side wall oxide layer for creating a lightly doped drain of a CMOS transistor.
