We present the process development and device characterization of the Selectively Compensated Collector (SCC) BJT specifically designed for high-density deep-submicrometer BiCMOS SRAM technologies. This double-poly BJT takes advantage of the self-ali

A theoretical study of the device characteristics of the Ge/sub x/Si/sub 1-x//silicon inversion-base transistor (BICFET) is presented. This transistor uses the space charge of holes in a modulation-doped inversion channel to control vertical electron

We present the performance improvements obtained both by scaling the Selectively Compensated Collector (SCC) BJT and by using a modified Current-Mode Logic (CML) gate configuration. Scaling the perimeter parameter by using the (tighter) bitcell desig

The first operational BICFET (bipolar-inversion-channel field-effect transistor) structures based on the Ge/sub x/Si/sub 1-x//Si system have been demonstrated. The 300 K current gains of beta >300 are believed to be the highest values reported for a

The authors demonstrate that the optimal 2-D collector doping profile for BiCMOS technologies is a strong function of the intended circuit application of the BJT (bipolar junction transistor). The 2-D collector doping profile in this study was tailor
