Abstract
Quasiplanar GaInP/GaAs heterojunction bipolar transistors (HBTs) with selective regrowth of the collector contact are reported. Such devices have a planar surface topology which should allow large scale integra tion. The multilayer HBT structure and the selective regrown collector contact are realised by chemical beam epitaxy (CBE). Cutoff frequency and maximum oscillation frequency of 30 and 25 GHz, respectively, hav e been obtained for devices with 2 x 15 mum2 emitter-base junction are a.
