Abstract:
A heterojunction bipolar transistor is integrated on radio frequency (RF) dies of different sizes. The heterojunction bipolar transistor includes an emitter on a first-side of a semiconductor-on-insulator (SOI) layer of an SOI substrate. The emitter is accessed from the first-side while a collector is accessed from a second-side of the SOI substrate. One or more portions of a base of the heterojunction bipolar transistor is between the emitter and one or more portions of the collector. The heterojunction bipolar transistor also includes a compound semiconductor layer between the collector and the emitter. The compound semiconductor layer carries a charge between the emitter and the collector.

Claim (Index 10):
A method of making a heterojunction bipolar transistor (HBT), comprising:\n fabricating an emitter on a first-side of a semiconductor-on-insulator (SOI) layer of an SOI substrate, the emitter accessed from the first-side; fabricating a collector accessed from a second-side of the SOI layer; and fabricating at least a portion of a base between the emitter and at least a portion of the collector, the base comprising a compound semiconductor layer including multiple sub-layers between the collector and the emitter, the compound semiconductor layer configured to carry a charge between the emitter and the collector, in which the collector comprises a first doped region and a second doped region with a different doping concentration, and in which at least one of the first doped region and the second doped region comprises a diffusion region.
