Abstract: A method is provided for fabricating a poly-poly capacitor integrated with a BiCMOS process. This includes forming a lower plate electrode of a poly-poly capacitor during deposition of a gate electrode of a CMOS transistor. An upper SiGe plate electrode is then formed during growth of a SiGe base region of a heterojunction bipolar transistor.

Abstract: A SiGe bipolar transistor containing substantially no dislocation defects present between the emitter and collector region and a method of forming the same are provided. The SiGe bipolar transistor includes a collector region of a first conductivity type; a SiGe base region formed on a portion of said collector region; and an emitter region of said first conductivity type formed over a portion of said base region, wherein said collector region and said base region include carbon continuously therein. The SiGe base region is further doped with boron.
