Abstract
A method and system for providing a bipolar transistor is described. The method and system include providing a compound base region including includes a compound box extension, providing an emitter region, and providing a collector region. The emitter region is coupled with the base region. The SiGe base region is coupled with the collector region and includes a SiGe box extension. The box extension resides substantially between the emitter and the heterogeneous base region.
