It is found that the Miller and feed-forward effects are enhanced with the reduction of the supply voltage. The reduction of the gate overlap capacitance as well as the threshold voltage and junction capacitance is a key issue to achieve high speed circuit operation at low supply voltage. We propose a low power, high speed T-gate CMOS device with dual gate structure using an amorphous-Si/poly-Si layer. A new process scheme is proposed to prevent boron penetration and to fabricate the T-gate structure effectively. It is found that the new T-gate CMOS with dual gate structure reduces the gate to drain overlap capacitance maintaining high current drivability at low power-supply voltage.","PeriodicalId":328379,"journal":{"name":"1995 Symposium on VLSI Technology.

The anomalous increase in the charge pumping current with decreasing channel length has been observed experimentally for the first time by using a charge pumping measurement. This is attributed to the enhanced nonuniform channel doping profile with the decreasing channel length as a result of the interstitial imperfections caused by OED or S/D implant. A simple and accurate model is proposed to determine the effective lateral nonuniform doping profile along the channel. The effective channel doping profile calculated from the new approach presents an obvious doping enhancement near the drain region of submicron devices by comparing with that of long channel devices. The simulated threshold voltages and I-V characteristics based on this profile show excellent agreement with the experimental data.","PeriodicalId":328379,"journal":{"name":"1995 Symposium on VLSI Technology.
