Classification: CPC H | IPC H

Claim 25:
26. An integrated circuit, comprising:
a semiconductor substrate having a top surface;
an electrode extending into the semiconductor substrate from the top surface to a collector region having a first conductivity type;
a base region having a different second conductivity type extending above the top surface over the collector region;
an emitter strip within the base region, the emitter strip having opposing short sides having a first width and opposing long sides, the emitter strip having the first conductivity type and a first majority carrier concentration;
a dielectric layer touching the top surface of the semiconductor substrate, a sidewall of the base region and a top surface of the emitter strip; and
a plurality of segmented emitter contacts arranged in a single column within the emitter strip and including a first emitter contact and a last emitter contact, each segmented emitter contact having a second width less than the first width and having the first conductivity type and a greater second majority carrier concentration, the segmented emitter contacts being spaced apart from nearest neighbor segmented emitter contacts by a portion of the emitter strip having the first majority carrier concentration, the segmented emitter contacts including a first segmented emitter contact in the column and a last segmented emitter contact in the column, the first and last segmented emitter contacts spaced apart from the respective short sides by a same first distance, and the first segmented emitter contact spaced apart from its nearest neighbor segmented emitter contact by a greater second distance and the last segmented emitter contact spaced apart from its nearest neighbor segmented emitter contact by the greater second distance.
