摘要：

A high speed bipolar transistor with high breakdown voltage BV(CEO) is described. The structure uses a composite collector of InGaAs and InP. A common emitter gain of 65 is obtained with a base doping of 7 x 10(19) cm-3 and a breakdown voltage in excess of 10 V. The f(T) = 64 GHz was reached at a collector-emitter voltage of 2 V and a current density of 52 kA/cm2. The potential of this structure for very high speed applications is demonstrated by the extracted intrinsic transit time of 0.4 ps.
