Patent ID: 7034397

Claim:
A method for manufacturing a semiconductor device, the method comprising in sequence, the steps of: providing a semiconductor substrate, the subs comprising first film being one of a diffusion barrier film and a metal film, the first film being exposed at least at part of the surface area of said substrate; exposing the substrate to an oxygen-containing reactant to create a surface termination of about one monolayer of oxygen-containing groups or oxygen atoms on the exposed parts of the first film wherein the oxygen-containing reactant is a hydroxyl-containing reactant and wherein the exposure with the hydroxyl-containing reactant is performed under ALD conditions to create a surface termination of about one monolayer of hydroxyl groups on the exposed parts of the first film;and depositing a second film onto the substrate, being the other of a diffusion barrier film and a metal film, such that the oxygen-containing groups or oxygen atoms form a bridge between the first film and the second film.
