摘要： A film forming method is disclosed in which a thin film comprising manganese is formed on an object to be processed which has, on a surface thereof, an insulating layer constituted of a low-k film and having a recess. The method comprises a hydrophilization step in which the surface of the insulating layer is hydrophilized to make the surface hydrophilic and a thin-film formation step in which a thin film containing manganese is formed on the surface of the hydrophilized insulating layer by performing a film forming process using a manganese-containing material gas on the surface of the hydrophilized insulating layer. Thus, a thin film comprising manganese, e.g., an MnOx film, is effectively formed on the surface of the insulating layer constituted of a low-k film, which has a low dielectric constant.

摘要： When a barrier film is formed on an exposed surface of an interlayer insulation film on a substrate, the interlayer insulation film having a recess formed therein, and a metal wiring to be electrically connected to a metal wiring in a lower layer is formed in the recess, a barrier film having an excellent step coverage can be formed and increase of a wiring resistance can be restrained. An oxide film on a surface of the lower copper wiring exposed to a bottom surface of the interlayer insulation film is reduced or edged so as to remove oxygen on the surface of the copper wiring. Then, by supplying an organic metal compound containing manganese and containing no oxygen, generation of manganese oxide as a self-forming barrier film is selectively allowed on an area containing oxygen, such as a sidewall of the recess and a surface of the interlayer insulation film, while generation of the manganese oxide is not allowed on the surface of the copper wiring. Thereafter, copper is embedded in the recess.
