An aluminum alloy (e.g., Al. 1%Si) film 16 is first formed by DC magnetron sputtering method on the film 15. Thereafter, a TiW film 17 of approx. 250Angstrom  thick is formed under the conditions that the formed film has a compression stress by a DC magnetron sputtering method on the film 16 in the same vacuum. In the case of the TiW, the internal stress in the film is determined by Ar pressure and power. Metal wirings (aluminum alloy film + TiW film) 18 is formed in lithography step. Then, an insulating film 19 is formed, and heat treated.
