Abstract
A semiconductor device includes a substrate including an isolation layer pattern and an active pattern, a buffer insulation layer pattern on the substrate, a polysilicon structure on the active pattern and the buffer insulation layer pattern, the polysilicon structure contacting a portion of the active pattern, and the polysilicon structure extending in a direction parallel to an upper surface of the substrate, a first diffusion barrier layer pattern on an upper surface of the polysilicon structure, the first diffusion barrier layer pattern including polysilicon doped with at least carbon, a second diffusion barrier layer pattern on the first diffusion barrier layer pattern, the second diffusion barrier layer pattern including at least a metal, and a first metal pattern and a first capping layer pattern stacked on the second diffusion barrier layer pattern.
