Abstract:
A method for production of a semiconductor device, comprising the steps of:forming at least a groove or hole in an insulation film formed on a substrate; stacking a metal film on said insulation film so as to bury the groove or hole; interposing an electrolytic solution between an electrode member and the metal film; oxidizing the surface of the metal film through an anode oxidation process; forming a chelate film of oxidized copper on the oxidated metal film; removing the chelate film from the surface of the metal film, wherein said chelate film is removed by wiping or mechanical polishing and the chelate film is wiped by a wiping member having an air hole; and selectively repeating the above step of removing the chelate film until the unevenness of the surface of the metal film is reduced.
