A semiconductor device has a multi-layer interconnection structure with a first interlayer insulation film and a second interlayer insulation film that is formed on the first interlayer insulation film and has a hardness and an elastic modulus larger than those of the first interlayer insulation film, and is fabricated by a step of forming a resist film on the second interlayer insulation film via an antireflective film, a step of exposing to light and developing the resist film to form a resist pattern, and a step of patterning the antireflective film and the multi-layer interconnection structure using the resist pattern as a mask, wherein a film with no stress or for storing compressive stress is used as the antireflective film.
