Abstract:
1. A segmented bipolar transistor, comprising: a substrate having a semiconductor surface; a p-base in said semiconductor surface including at least one p-base finger comprising a base metal/silicide stack including a base metal line that contacts a silicide layer on said semiconductor surface of said p-base finger; an n+ buried layer under said p-base in said semiconductor surface; a collector including an n+ sinker diffusion lateral to said p-base extending from said semiconductor surface to said n+ buried layer including a collector finger comprising a collector metal/silicide stack including a collector metal line that contacts a silicide layer on said semiconductor surface of said collector finger, and an n+ emitter within a portion of said p-base including at least one emitter finger comprising an emitter metal/silicide stack including an emitter metal line that contacts a silicide layer on said semiconductor surface of said emitter finger; wherein said emitter metal/silicide stack includes segmentation comprising an emitter gap in said emitter metal line or in said silicide layer on said semiconductor surface of said emitter, or said collector metal/silicide stack includes segmentation comprising a collector gap in said collector metal line or in said silicide layer on said semiconductor surface of said collector finger.
