Abstract:
A silicon-on-insulator (SOI) CMOS transistor and a SOI heterojunction bipolar transistor (HBT) are fabricated on the same semiconductor substrate. First and second SOI regions are formed over the semiconductor substrate. A SOI CMOS transistor is fabricated in the first SOI region, and a collector region of the SOI HBT is fabricated in the second SOI region. The collector region can be formed by performing a first implant to a local collector region in the second SOI region, and performing a second implant to an extrinsic collector region in the second SOI region, wherein the extrinsic collector region is separated from the local collector region. A SiGe base is formed over the collector region, wherein a dielectric structure separates portions of the SiGe region and the extrinsic collector region. The SOI CMOS transistor and SOI HBT may be used to implement a front end module of an RF system.

Claim (Index 2):
The method of  claim 1 , wherein fabricating the collector region comprises:\n performing a first implant to introduce an impurity of a first conductivity type into a local collector region in the second SOI region; and performing a second implant to introduce an impurity of the first conductivity type into an extrinsic collector region in the second SOI region, wherein the extrinsic collector region is separated from the local collector region.
