Embodiments described herein include methods of forming metal silicide layers using a diffusionless annealing process. In one embodiment a method for forming a metal silicide material on a substrate is provided. The method comprises depositing a metal material over a silicon containing surface of a substrate, depositing a metal nitride material over the metal material, depositing a metallic contact material over the metal nitride material, and exposing the substrate to a diffusionless annealing process to form a metal silicide material. The short time-frame of the diffusionless annealing process reduces the time for the diffusion of nitrogen to the silicon containing interface to form silicon nitride thus minimizing the interfacial resistance.
