Abstract: PROBLEM TO BE SOLVED: To obtain a formation method in which pores in a wiring film formed by a plating method, a chemical vapor deposition method or the like can be made to disappear under a low pressure, by a method wherein the surface of an insulating film on a substrate in which a hole and a groove are formed is covered with copper or a copper alloy, the inside of the hole and that of the groove are filled with a metallic material, and the wiring film is formed. SOLUTION: A polycrystalline copper film which is composed of fine copper crystal particles is heated and treated under atmospheric pressure or in a high-pressure gas atmosphere, and a wiring film 4 is formed. Fine pores are interposed between the fine copper crystal particles. When the polycrystalline copper film is heated under atmospheric pressure or in a vacuum, the copper crystal particles are grown. Several pores are gathered, and large pores 5 are formed. The diameter of an actual hole 2A and the width of a groove are at 0.2 μm or lower. A region which is at 0.1 μm or lower is effective in growing the crystal particles. When a substrate 1 is maintained at about room temperature even by a PVD method, the film is formed of the crystal particles. The substrate 1 is cooled in a film formation operation in order to prevent that particles which are stuck later become large.  The temperature of the substrate can be controlled by a CVD method, and the film which is composed of the fine crystal particles can be obtained at room temperature by a plating method.
