Abstract

This invention provides a process for producing a semiconductor device, comprising the step of forming a seed layer, formed of a self-forming barrier metal or an alloy of the metal with copper which is converted to an oxide to develop a copper diffusion preventive function, on an interlayer insulation film on the surface of a substrate and along the inner wall surface of its concave part, the step of reducing the seed layer with an active species of hydrogen, the step of, after the reduction of the seed layer, embedding copper in the concave part, and the step of, after embedding of copper, oxidizing the self-forming barrier metal constituting the seed layer to form a barrier layer and heating the substrate in an oxygen atmosphere to deposit excess self-forming barrier metal on the surface of copper. In this case, after the reduction of the seed layer, the substrate is placed in a vacuum atmosphere or an inert gas atmosphere until copper is embedded in the concave part.
