An experimental study is conducted which shows that a thin interposing Pt layer was found to act as a diffusion barrier and suppress the diffusion of Ni atoms effectively at temperatures below 500 °C. It indicates that NiSi phase can be stabilized by the presence of a thin Pt layer and the thermal stability of NiSi was improved considerably. The sheet resistance maintained the same low level in a wide temperature range. NiSi was found to be the only silicide phase for the Ni/Pt bilayer on (001)Si samples after annealing at 500-800 °C.
