摘要： A bipolar transistor is provided which is of high reliability and high gain, and which is particularly suitable to high speed operation. The bipolar transistor operates with high accuracy and with no substantial change of collector current even upon change of collector voltage. It also has less variation than conventional bipolar transistors for the collector current while ensuring high speed properties and high gain. In one example, the band gap in the base region is smaller than the band gap in the emitter and collector regions. The band gap is constant near the junction with the emitter region and decreases toward the junction with the collector region. A single crystal silicon/germanium is a typically used for the base region.

摘要： A high-speed bipolar transistor is provided which is improved in the effect of heat radiation without increasing the substrate capacitance. The heat radiation connection between a base region and a silicon substrate includes a p+ extrinsic base polysilicon electrode and a polysilicon layer buried in an isolation groove with a very thin silicon dioxide side wall. Accordingly, the heat generated at the base is radiated through this path to the silicon substrate. Further, the film thickness of the silicon dioxide on the inner wall of the isolation groove is sufficiently increased compared with previous structures to prevent an increase in the substrate capacitance. Consequently, there can be obtained a bipolar transistor which operates at high speed, and is improved in the effect of heat radiation without increasing the substrate capacitance.
