摘要
Avalanche breakdown behavior at the collector junction of the GaAs/AlGaAs heterojunction bipolar transistor (HBT) has been studied. Junction breakdown characteristics displaying hard break-down, soft breakdown, and negative resistance breakdown behavior were observed and are interpreted by analysis of localized micro-plasma effects, uniform microplasma-free behavior, and associated current gain measurements. Light emission from the collector-base junction of the GaAs/AlGaAs HBT was observed and was used to investigate breakdown uniformity. Using a simple punchthrough break-down model, the theoretical breakdown curves at different collector doping concentrations and thicknesses were computed and found to be in agreement with maximum breakdown voltages measured from de-vices displaying the most uniform junction breakdown.
