摘要：A bipolar transistor structure comprises a semiconductor substrate having a first conductivity type, a collector region having a second conductivity type that is opposite the first conductivity type formed in a substrate active device region defined by isolation dielectric material formed in an upper surface of the semiconductor substrate, a base region that includes an intrinsic base region having the first conductivity type formed over the collector region and an extrinsic base region having the second conductivity type formed over the isolation dielectric material, and a sloped in-situ doped emitter plug having the second conductivity type formed on the intrinsic base region.
