    摘要: Bridging between nickel suicide layers on a gate electrode and source/drain regions along silicon nitride sidewall spacers is prevented by treating the exposed surfaces of the silicon nitride sidewall spacers with a nitrogen plasma to create a surface region having reduced free silicon. Embodiments include treating the silicon nitride sidewall spacers with a nitrogen plasma to reduce the refractive index of the surface region to less than about 1.95.

    摘要: Bridging between nickel silicide layers on a gate electrode and source/drain regions along silicon nitride sidewall spacers is prevented by treating the exposed surfaces of the silicon nitride sidewall spacers with a plasma containing ammonia and nitrogen to create a clean surface region having increased nitrogen. Embodiments include treating the silicon nitride sidewall spacers with an ammonia and nitrogen plasma to reduce the refractive index of the surface region to less than about 1.95.

    摘要: Bridging between nickel silicide layers on a gate electrode and source/drain regions along silicon nitride sidewall spacers is prevented, after silicidation and removal of any unreacted nickel, by treating the exposed surfaces of the silicon nitride sidewall spacers with a HDP plasma to oxidize nickel silicide thereon forming a surface layer comprising silicoin oxide and silicon oxynitride. Embodiments include treating the silicon nitride sidewall spacers with a HDP plasma to form a surface silicon oxide/silicon oxynitride region having a thickness of about 40 Å to about 50 Å.
