Abstract

The reliability of InGaP/GaAs N–p–n heterojunction bipolar transistors (HBTs) with different base metal contact systems (Au/Zn/Au, Ti/Au, Ti/Pt/Au and the novel Ti/ZrB2/Au) undercurrent and temperaturestress is studied in this paper. We further report results of currentstress on three p-GaAs doping impurities namely Zn, Be and C. The effect of O+/H+ and O+/He+ ions, used in the fabrication of planar self-aligned HBTs, is also investigated in the stability of device dc current gain. The instability phenomena typical of each factors and their effects on the HBT characteristics are repor
