A new InGaP/GaAs double delta-doped heterojunction bipolar transistor (D3HBT) has been fabricated successfully and demonstrated. Due to the employment of delta-doped sheets, the potential spikes at emitter-base (E-B) and base-collector (B-C) heterojunctions are suppressed considerably. Therefore, good transistor performance including higher current gain and lower knee voltage are obtained.
