Abstract

Self-aligned high-frequency InP/InGaAs double heterojunction bipolar transistors (DHBT's) have been fabricated on a Si substrate for the first time. A current gain of 40 was obtained for a DHBT with an emitter dimension of 1.6 × 19 μm². The S parameters were measured for various bias points. In the case of I_c= 15 mA, f_Twas 59 GHz at V_CE= 1.8 V, and fmax ^was 69 GHz at V_CE = 2.3 V. Due to the InP collector, breakdown voltage was so high that a high V_CEof 3.8 V was applied for I_c = 7.5 mA in the S-parameter measurements to give an f_Tof 39 GHz and an f_max of 52 GHz.
