Abstract

A method of producing a semiconductor device, which includes applying a conductive metal film on a semiconductor wafer, applying a photoresist on the conductive metal film, removing the photoresist with a removing agent containing a fluorine compound or at least one basic component selected from the group consisting of a quaternary ammonium hydroxide, an alkanolamine and a mixture of an alkanolamine and a reducing agent, and cleaning the resultant semiconductor device by rinsing with a rinse comprising water and at least one peroxide compound. The method of the present invention can provide a highly accurate wiring circuit without corrosion of the conductive metal film.
