摘要: A semiconductor device including a conductive layer, a diffusion barrier layer formed over the conductive layer, including a refractory metal compound, and acquired after a surface treatment, and a metal silicide layer formed over the diffusion barrier layer. The adhesion between a diffusion barrier layer and a metal silicide layer may be improved by increasing the surface energy of the diffusion barrier layer through a surface treatment. Therefore, although the metal silicide layer is fused in a high-temperature process, it is possible to prevent a void from being caused at the interface between the diffusion barrier layer and the metal silicide layer. Moreover, it is possible to increase the adhesion between a conductive layer and the diffusion barrier layer by increasing the surface energy of the conductive layer through the surface treatment.
