Distribution and migration characteristics of fluorine in poly-Si gate on BF2+ implanted poly-Si gate with an energy of 80 keV and doses of 2×1015 cm-2 under conventional thermal annealing has been analyzed systematically and deeply by SIMS.Migration of fluorine in poly-Si gate exists not only diffusion mechanism,but also absorption and emission mechanism,and experiment results are explained successfully.
