Abstract: A Cu—Ni—Mo alloy thin film, including Ni as a solution element and Mo as a diffusion barrier element. Ni and Mo are co-doped with Cu. The enthalpy of mixing between Mo and Cu is +19 kJ/mol, and the enthalpy of mixing between Mo and Ni is −7 kJ/mol. The atomic fraction of Mo/Ni is within the range of 0.06-0.20 or the weight faction of Mo/Ni within the range of 0.10-0.33. The total amount of Ni and Mo additions is within the range of 0.14-1.02 at. % or wt. %. A method for manufacturing the alloy thin film is also provided.
