A leading edge 130 nm technology with 6 layers of Cu interconnects and 1.3 V operation has previously been presented (Tyagi et al., 2000). In this work, we enhance the previous technology with the following: transistor improvements which support a 60 nm gate dimension and increased drive current, improved 6-T SRAM device matching to allow low power and high performance operation from 0.7 to 1.4 V, and a 5% linear shrink to reduce the 6-T SRAM cell to 2.00 μm2 while still using 248 nm lithography. Saturation drive currents of 1.30 mA/μm for N-channel and 0.66 mA/μm for P-channel low VT devices are the highest reported to date. Excellent device short channel effects are obtained for the 60 nm gate length devices as measured by the 270 mV threshold voltage and <100 mV/V DIBL. These results have been achieved on both 200 and 300 mm wafers
