ABSTRACT:
An embodiment of the present invention is a process for semiconductor device having a silicon substrate. The process comprises positioning at least one field implant mask and field implanting a silicon substrate around a bipolar active region in a substrate such that boron atoms are blocked out of an active region, and only the field region surrounding said active area is implanted, said implanting such that a predetermined layout area of a semiconductor device does not need to be increased to compensate for a BV.sub.bso problem.
