Abstract :
To lower C content can keep performance enhancement of strained-Si:C devices since it minimizes the alloy scattering potential, interstitial trap and Dit. The large Dit at oxide/strained-Si:C interface degrades the expected carrier mobility enhancement, but improvement is observed after forming gas annealing. The strained-Si:C channel makes it possible to have high speed devices, improved short channel effect, and extremely shallow S/D junctions
