ABSTRACT:
An improved semiconductor device is presented, the improvement comprising a slot collector contact region (38). The slot collector contact region (38) is formed in a semiconductor substrate (39) adjacent to base and emitter regions (40,44) of the bipolar semiconductor device. The slot collector contact region (38) is comprised of a slot filled with a filler material. In a preferred embodiment of the invention, the slot collector contact region (38) is separated from the base and emitter regions (40,44) by an insulating layer (52).
