Abstract :
In this paper the effects of highly non-uniform collector doping profiles on the speed and breakdown performance of silicon bipolar transistors are investigated by means of Monte Carlo and drift diffusion simulations. The results point out that a thin highly-doped collector layer adjacent to the base can improve the speed of the intrinsic device without a significant reduction of breakdown voltage. Guidelines for choosing the target doping level and layer thickness are provided.
