Abstract :
The authors present the process optimization and device characteristics of a half-micron super self-aligned BiCMOS technology. With a new emitter/base process in their BiCMOS flow, bipolar transistor power gain cutoff frequency, fmax, has been increased from 25.9 GHz to 33.5 GHz. Since all the process parameters related to CMOS are kept constant, high speed CMOS circuit operation is maintained without compromise. The measured nominal CMOS gate delay with a gate length of 0.5 mu m is 47 psec at 5V and 54 psec at 3.3V.
