80 nm CMOSFET technology using double offset-implanted source/drain extension and low temperature SiN process

Double offset-implanted source/drain extension and 550/spl deg/C silicon nitride deposition for sidewall and borderless contact have been applied to sub-0.1 /spl mu/m CMOS for improvement of short channel effect as well as parasitic resistance. Consequently, 830/400 /spl mu/A//spl mu/m drive current with 2.5 nm gate insulator has been achieved under 1 nA//spl mu/m off-leakage at 1.5 V operation with short channel tolerance to 80 nm gate length.
