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.
