A cost-conscious 32nm CMOS platform technology with advanced single exposure lithography and gate-first metal gate/high-k process

For the first time, we demonstrate standard cell gate density of 3650 KGate/mm 2 and SRAM cell of 0.124 mum 2 for 32 nm CMOS platform technology. Both advanced single exposure (SE) lithography and gate-first metal gate/high-k (MG/HK) process contribute to reduce total cost per function by 50% from 45 nm technology node, which is unattainable by dual exposure (DE) lithography or double patterning (DP) and poly/SiON gate stack.
