  • Publication number: 20070099805
    Abstract: Improved stripper solutions for removing photoresists from substrates are provided that typically have freezing points below about +15° C. and high loading capacities. The stripper solutions comprise dimethyl sulfoxide, a quaternary ammonium hydroxide, and an alkanolamine having at least two carbon atoms, at least one amino substituent and at least one hydroxyl substituent, the amino and hydroxyl substituents attached to two different carbon atoms. Some formulation can additionally contain a secondary solvent. Methods for use of the stripping solutions are additionally provided.
