Doping Cu with some elements has been proved to be a promising method to improve the reliability of Cu interconnects. In this paper, Ag was chosen as the alloying element because of its low bulk resistivity and low solubility in Cu. Cu–Ag alloy film was prepared by layered evaporation and postdeposition annealing in vacuum. The resistivity of the films decreased with annealing temperature. After annealing at 400°C, most of the Ag atoms were segregated to the film surface because Cu–Ag system had a negative segregation energy. By comparing the texture evolution of pure Cu film and Cu–Ag films during annealing, it was found that Ag addition usually retarded the texture development of the alloy film. Vacuum annealing resulted in a rougher surface for the Cu–Ag films. The investigation of alloying effect on Cu agglomeration on TaN substrate suggested that Ag addition might impair the Cu wettability on TaN substrate. Possible methods for improving the surface morphology of Cu alloy were also proposed.
