Incorporation of carbon in silicon/silicon germanium epitaxial layer to enhance yield for Si-Ge bipolar technology
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.
