In this paper, thermal stability in the multifinger GaInP/GaAs collector-up tunneling-collector heterojunction bipolar transistors (C-up TC-HBTs) has been investigated. Two unique structures in these(More)
A novel structure of InGaP/GaAs collector-up tunneling-collector heterojunction bipolar transistors (C-up TC-HBTs) with sub-transistor via-holes, for use in small power amplifiers, is presented.(More)
