A 70 nm gate length CMOS technology with 1.0 V operation

A 70-nm gate length CMOS technology for 1.0 V operation has been developed. This technology realizes high performance CMOS roadmap trend and utilizes sub-1 keV ion implantation for source/drain extension formations, quick-cooling RTA process, and ultra-thin gate dielectrics of 1.3 nm. The thickness of the gate dielectrics has been optimized in terms of both the I/sub ON/-I/sub OFF/, tradeoff and gate delay metrics. Obtained I/sub D//sup SAT/ for nMOS and pMOS are 723 /spl mu/A//spl mu/m (I/sub OFF/=16 nA//spl mu/m) and 290 /spl mu/A//spl mu/m (I/sub OFF/=20 nA//spl mu/m), respectively.
