| description | The present invention addresses the problem of providing a photoresist stripping composition that exhibits a high stripping performance even with respect to a hardened resist, and that, even when the amount of water in the make-up is small, experiences little decrease in stripping performance when water evaporates and makes it possible to inhibit corrosion of a substrate-constituting metal that comes into contact with a liquid, such as Cu, Al, or Si. The above is accomplished by a photoresist stripping composition containing (A) a quaternary ammonium hydroxide, (B) a sugar alcohol, (C) an amine, (D) water, (E) DMSO, and (F) ethylene glycol, the (D) water content being 1.0-10 mass% relative to the total mass of the composition. |
