We report a very high performance 100 nm gate length CMOS transistor structure operating at 1.2-1.5 V. These transistors are incorporated in a 180 nm logic technology generation. Various process enhancements are incorporated to significantly improve transistor current drive capability relative to the results published by Yang et al. (1998). Unique transistor features responsible for achieving high performance are described. NMOS and PMOS devices demonstrate drive current of 1.04 mA//spl mu/m and 0.46 mA//spl mu/m respectively at 1.5 V and 3 nA//spl mu/m I/sub OFF/. These are the best drive currents reported to date at fixed I/sub OFF/. They represents 10% drive current improvement for both NMOS and PMOS devices relative to the results published by Yang without any change in gate-oxide thickness. High performance is demonstrated down to 1.2 V. Inverter delay of less than 10 psec is reported at 1.5 V at very moderate I/sub OFF/ values.
