Assignee: TEXAS INSTRUMENTS INCORPORATED
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An integrated circuit, comprising:
a collector including a collector region having a first conductivity type extending into a semiconductor substrate having a top surface;
a base including a base region located above the top surface of the semiconductor substrate and having a different second conductivity type;
an emitter including an emitter strip within the base region, the emitter strip having a first width and comprising a first dopant with the first conductivity type and having a first dopant concentration;
a dielectric layer touching the top surface of the semiconductor substrate, a sidewall of the base region and a top surface of the base region; and
a plurality of segmented emitter contacts in a single column within the emitter strip, each segmented emitter contact having a second width less than the first width and comprising a second dopant with the first conductivity type and having a greater second dopant concentration, each segmented emitter contact being spaced from a nearest neighbor segmented emitter contact by a portion of the emitter strip.
