Abstract

The carbon incorporation in strained-Si source/drain of MOSFET is demonstrated. The methylsilane (CH ₃ SiH ₃ ) is chosen as the carbon precursor to make high percentage of substitutional carbon, and less defects by interstitials and vacancies. The large D _it at oxide/strained-Si:C interface degrades the expected carrier mobility enhancement, but improvement is observed after forming gas annealing. The strained-Si source/drain with carbon incorporation is not only being stressor but also lower R _s , and make a potential candidate for future high-speed ballistic devices beyond 10 nm technology node.
