Abstract :
A model is developed for the current gain of submicrometre bipolar transistors. The model takes into account the actual shape of the emitter-base junction and the effect of carrier recombination at the interface between the intrinsic and extrinsic base, allowing analytical interpretation of the beta dependence on emitter size and spacer geometry.
