Abstract
Nickel silicide formation with significantly reduced interface roughness is achieved by forming a diffusion modulating layer between the underlying silicon and nickel silicide layers. Embodiments include ion implanting nitrogen into the substrate and gate electrode, depositing a thin layer of titanium or tantalum, depositing a layer of nickel, and then heating to form a diffusion modulating layer containing nitrogen at the interface between the underlying silicon and nickel silicide layers.
