Abstract :
This paper presents a 86 GHz fT, 105 GHz fmax BiCMOS technology without compromising 0.13 μm gate length CMOS characteristics. This SiGe BiCMOS technology can be realized without adopting any bipolar-oriented process such as collector epitaxial growth and deep trench isolation (DTI). The following are the features of this technology: (1) a tungsten plug trench collector sink is used to reduce the collector resistance of the epi-free collector; (2) base and emitter profiles are optimized for the simultaneous RTA treatment for both emitter drive-in and CMOS S/D annealing; (3) SiGe HBTs are fabricated using our original double-poly self-aligned technology using selective epitaxial SiGe growth.
