METHOD FOR FORMING A COPPER FILM ON A SUBSTRATE

Adhesion of a copper film, such as a copper interconnect, to a substrate underlayer, such as a substrate diffusion barrier, is enhanced with adhesion promotion techniques. The adhesion promotion techniques can repair the interface of the copper film and the substrate to enhance adhesion of the coppe...
