  • Bipolar transistor, semiconductor device and method of manufacturing same
    Publication number: 20040046187
    Abstract: The bipolar transistor comprises a collector region (1) of a semiconductor material having a first doping type, a base region (2) of a semiconductor material having a second doping type, and an emitter region (3) having the first doping type. A junction is present between the emitter region (3) and the base region (2), and, viewed from the junction (4), a depletion region (5) extends into the emitter region (3). The emitter region (3) comprises a layer (6) of a first semiconductor material and a layer (7) of a second semiconductor material.
