Method of producing metal film |
摘要 |
Concentration of electric current due to an additive (particularly, a brightener) remaining or precipitated in a high concentration at grain boundary triple points and wiring groove portions in the surface layer of a copper plating film is obviated, whereby precedent dissolution and/or abnormal dissolution due to concentration of electric current is restrained, and an electropolished surface of the copper plating film with excellent surface smoothness is obtained. A method of producing a metallic film includes the steps of: forming a metallic plating film (copper plating film (15)) by use of a plating solution prepared by adding a plating additive for restraining void generation, bottom-up fill and overfill; and electropolishing the metallic plating film by use of an electropolishing solution prepared by adding a polishing additive capable of reacting or coupling with the plating additive component contained or precipitated in the surface layer of the metallic plating film.
