A method for BICMOS devices is disclosed, wherein an emitter and a base of a vertical PNP transistor are self-aligned, an extrinsic base is formed by adapting a base electrode polysilicon layer as a diffusion source, and the base electrode and an intrinsic base are coupled by diffusion of N type impurities adapting the N.sup.+ polysilicon as a diffusion source, so that the manufacturing process is simplified and the resistance of the extrinsic base is reduced.
