Abstract

Without inducing any degradation of CMOS performance and reliability, a high performance self-aligned SiGe-HBT process was successfully integrated to a standard 0.13-μm CMOS platform including dual gate oxides and five layers of Al metallization. Suppressing moisture elimination from a wafer surface is a key for reducing thermal budgets during the SiGe HBT formation process. We found that a heavily boron-doped intrinsic base that is highly activated by 1000-°C RTA improved HBT performance with low rbb' of 82 ω and high fT/ fmax of 122/178 GHz.
