Claim:
1. A method of manufacturing a conductive structure, comprising steps of: forming a barrier metal film on a substrate and a copper metal film on the barrier metal film, such that the copper metal film is laminated on the barrier metal film; forming a preset photoresist pattern on the copper metal film after forming the preset photoresist pattern; etching the barrier metal film and the copper metal film; oxidizing an exposed sidewall of the etched barrier metal film and an exposed sidewall of the etched copper metal film after the step of etching the barrier metal film and the copper metal film, so as to generate metal oxide layers on the exposed sidewall of the etched barrier metal film and the exposed sidewall of the etched copper metal film, respectively; and stripping off the photoresist pattern by means of a photoresist stripping liquid after the oxidizing step.
