ABSTRACT:
An integrated circuit bipolar transistor is described wherein the relative semiconductor electrode areas are established by an electrode pedestal that includes a base contact positioning feature and wiring constraints are relaxed by a base pedestal that facilitates the positioning of contact wiring that is independent of contact location. A heterojunction bipolar transistor having a base area less than twice as large as the emitter area is described.
