Hydrogen-induced transient effect in carbon-doped InGaP hetero-junction bipolar transistors
The transient effect on the current gain of InGaP hetero-junction bipolar transistors was studied. It was found that this transient effect was caused by hydrogen and eliminated after three or more cycles of thermal annealing at 250C in nitrogen. A model based on the carbonhydrogen complex dissociation by thermal anneal is proposed to explain this observation.
