A novel approach for the patterning and high-volume production of sub-40-nm gates
2005
A novel approach for the patterning and manufacturing of sub-40-nm gate structures is presented. Rather than using resist or an inorganic hardmask as the patterning layer, this gate patterning scheme uses an amorphous carbon (a:C) and cap hardmask to pattern small gates. Healthy and manufacturable gate lengths have been achieved below 35 nm with this scheme, and the potential exists for further extendibility.
