Abstract :
In this paper, a modified silicon heterojunction bipolar transistor is proposed and demonstrated. The structure uses a very thin n/sup +/ amorphous silicon layer as the emitter to enhance the emitter injection efficiency and reduce the emitter resistance as well as improve the frequency response of the device.<>
