Abstract
The formation of metal oxide contaminants on the surfaces of thin metal films by out-diffusion primarily through the grain boundaries thereof of metal from an underlayer is inhibited by conducting heat cycling of such layered metal structures in an ambient gas mixture composed of inert gas, such as nitrogen, containing a sufficient amount of active gas, such as, hydrogen, carbon monoxide, or the like, substantially to suppress such out-diffusion.
