Abstract :
SiGe HBT Bipolar/BiCMOS technology has a unique opportunity in the wireless marketplace because it can provide the performance of III-V HBTs and the integration/cost benefits of silicon bipolar/BiCMOS. This paper will review the status of IBM´s SiGe HBT technology particularly focusing on some key device and application issues for high frequency circuit applications. In this work we review graded-base SiGe HBTs optimized for analog circuits and address four key issues: 1) BVceo constraints, 2) Transmission line loss, 3) Noise performance, and 4) Process integration leverage and issues. All of the hardware results are for self-aligned, polysilicon emitter, graded-base SiGe HBTs fabricated in a 200 mm semiconductor production line using the UHV/CVD technique for film growth
