Paper Abstract

This paper describes a new method to improve the base- collector breakdown voltage of high frequency NPN bipolar transistor. It consists of introducing a suitable P floating region in the N collector by ion implantation or by molecular beam epitaxy. The basic profile of the intrinsic transistor is not changed. Computer device simulations show that a nearly 20% improvement of the base-collector breakdown voltage can be achieved in a common emitter configuration. Additional advantages are a reduction of the multiplication factor and an enhanced impact-ionization base current reversal voltage.
