Shown in In the case of the substrate shown in FIG. 3 (a-1), the Cu film is peeled off (for example, portion A in the figure).

On the other hand, in the case of the substrate shown in FIG. 3B-1, the boundary layer is not observed by the heat treatment at 350 ° C. As a result of Auger analysis, it is considered that Cu diffused into the Ti film by heat treatment to form an alloy.

- the Cu wiring film formed after the heat treatment at 250 ° C. has very good adhesion between the Cu wiring film and the Co film, no voids are formed in the Cu wiring film, and SM resistance and EM resistance are prevented. Such wiring reliability can be improved.
- the Co film has a thinner boundary layer (about half) than the Ti film, and as a result, the Co film adheres even at a heating temperature as low as 250 ° C. compared to the heating temperature of 350 ° C. in the case of the Ti film.
- a heating temperature as low as 250 ° C. compared to the heating temperature of 350 ° C. in the case of the Ti film.
- This property that the boundary layer becomes thin is thought to be due to the property that Co is less oxidized than Ti.

- a film selected from Ti, TiN, Ta, TaN, W, WN, and silicide can be used, and it is desirable that the barrier film be uniformly formed in fine trenches and holes. . Therefore, asymmetry and overhang do not easily occur during film formation, and W and TiN films formed by an ALD method or a CVD method to form a uniform film are preferable, and a TiN film is optimal.
- the substrate can be used without particular limitation as long as it is used for a semiconductor device.
- a 3 nm TiN barrier film was formed by Cat-ALD method (raw material: TiCl 4 , film formation temperature: 350 ° C., film formation pressure: several Pa to several tens Pa).
- the ALD-TiN barrier film is formed, it is exposed to the atmosphere, and then a Co film is formed to 5 nm by the PVD method (film formation temperature: 25 ° C., film formation pressure: 0.5 Pa).
- a Cu film was formed to a thickness of 100 nm at a temperature of 200 ° C.
- the heat treatment after forming the Cu film was performed at 200 ° C. and 300 ° C. for 1 hour, respectively. In this case, as described above, no void was generated in the Cu film, and the CVD-Cu film was embedded in the hole without any gap.
- Co film formation was performed under the conditions of 150 Pa and 270 ° C. by a CVD method using a Co raw material such as Co (CH 3 C 5 H 4 ) 2 instead of the PVD method in Example 1.
