  • Abstract
    We demonstrate a novel photoresist-compatible FinFET doping technique that combines the advantages of deposition and implantation. Energy and deposition thickness optimization for the Ion Assisted Deposition and Doping (IADD) process provides excellent doping of nMOS extensions, thus reducing external resistance REXT. On current ION is improved by 6-8% for LG of 26-30 nm and by 15% for LG of 20 nm, with better SCE and DIBL.
