According to one embodiment, a method is disclosed for chemical planarization. The method can include forming a surface layer on a to-be-processed film having irregularity. The surface layer binds to or adsorbs onto the to-be-processed film along the irregularity to suppress dissolution of the to-be-processed film. The method can include planarizing the to-be-processed film in a processing solution dissolving the to-be-processed film, by rotating the to-be-processed film and a processing body while the to-be-processed film contacting the processing body via the surface layer, removing the surface layer on convex portions of the irregularity while leaving the surface layer on concave portions of the irregularity and making dissolution degree of the convex portions larger than dissolution degree of the concave portions.

According to one embodiment, a method of manufacturing a semiconductor device is provided. In the method, a groove is formed in a insulating film on a semiconductor substrate. An underlayer film is formed on the insulating film. A metal film is formed on the underlayer film. First polishing, in which the metal film is removed, is performed by supplying a first CMP slurry containing metal ions. The surfaces of the polishing pad and the semiconductor substrate are cleaned by supplying organic acid and pure water. Second polishing, in which the underlayer film is removed from the portion other than the groove, is performed by supplying a second CMP slurry different from the first CMP slurry.
