Abstract: A first interconnection is formed in a first interlayer insulating film. An etching stopper film is formed on the first interconnection. On the etching stopper film, a second interlayer insulating film and an anti-reflective coating are successively formed, and a via hole penetrating the second interlayer insulating film and the anti-reflective coating to reach the etching stopper film is formed. An organic film is formed in the via hole, and a trench reaching the organic film is formed in the second insulating film. By removing the anti-reflective coating and the etching stopper film at the bottom portion of the via hole, a portion of the surface of the first interconnection is exposed, and a second interconnection is formed in the trench and the via hole.
