  • Abstract
    The bias-stress reliability of MOCVD grown C-doped AlGaAs/GaAs HBTs were studied. We found that B/E heterojunction is very stable in agreement with the literature. However, current gain degradation was found to be device dependent. Further more, we found that the B/C metallurgical degrades with stress, leading to device failure.
