A part of the exposed lower metal wire is etched. An adhesive layer(281) is formed on the etched lower metal wire with a uniform thickness. A first diffusion prevention layer is formed on the adhesive layer, so the lower metal wire where the adhesive is formed is buried. The first diffusion prevention layer and the adhesive layer are surface-processed. A second diffusion prevention layer(284) is formed on the via hole including the surface-processed first diffusion prevention layer and the adhesive layer, and formed on the entire surface of the trench with a uniform thickness. An upper metal wire(291) including a via contact(290) is formed in the via hole and the trench in which the second diffusion preventive layer is formed.
