摘要： Disclosed is a method for stripping a photoresist comprising: (I) providing a photoresist pattern on a substrate where the substrate has at least a copper (Cu) wiring and a low-dielectric layer thereon, and selectively etching the low-dielectric layer by using the photoresist pattern as a mask; (II) contacting the substrate after the step (I), with ozone water and/or aqueous hydrogen peroxide; and (III) contacting the substrate after the step (II), with a photoresist stripping solution that contains at least a quaternary ammonium hydroxide. The present invention provides a method for stripping a photoresist that enables to strip effectively photoresist films and etching residues after etching step even in a process not including an O2 plasma ashing treatment in micropatterning of a substrate having at least Cu wiring and a low-dielectric layer thereon, as in a dual damascene forming process, and, in addition, the method of the invention does not have any negative influence on the dielectric constant of the low-dielectric layer, and ensures an excellent anti-corrosivity.
