The conductor diffusion-preventing film is formed using Ta or TaN. The photo resist film is patterned using a reverse mask, and thus a photo resist pattern is formed on the damascene pattern. The diffusion -preventing film remains only on the damascene pattern by removing the revealed conductor diffusion-preventing film. After removing the photo resist pattern, a copper layer(13) is formed on the whole structure to bury the damascene pattern. After polishing the copper layer until an upper surface of the interlayer insulation film is revealed by a CMP(Chemical Mechanical Polishing) process using a slurry for polishing a copper, a copper line is formed in the damascene pattern by buffering or cleaning the copper layer in the CMP apparatus.
