Patent ID: 7846839

Claim:
A film forming method of forming a Cu film on a substrate to be processed, comprising: a first step of forming an adhesion film on a Cu diffusion barrier film formed on the substrate to be processed; and a second step of forming the Cu film on the adhesion film, wherein the adhesion film includes Pd, the adhesion film is formed by a chemical vapor deposition (CVD) method with a Pd film forming gas and a Pd reducing gas, the Cu film is formed by a CVD method with a Cu film forming gas and a Cu reducing gas, and the Cu film forming gas is selected from a group consisting of Cu(hfac) 2 , Cu(acac) 2 , Cu(dpm) 2 , Cu(dibm) 2 , Cu(ibpm) 2 , Cu(edmdd) 2 , Cu(hfac)TMVS and Cu(hfac)COD.
