    Abstract: A novel stripping composition and method of using same is disclosed, which stripping composition comprises:

    a) a solvent comprising one or more compounds of formula (I)
    wherein R and R' are each selected independently from straight and branched alkyl having 1 to 3 carbon atoms, and phenyl, each of which phenyl is optionally substituted with one or more hydroxyl, or R and R' together are alkylene of 3 to 6 carbon atoms; and
    b) a suitable organosulfonic acid.

    The stripping composition is especially useful for stripping positive photoresists faster and at lower temperatures than known strippers. A preferred composition comprises 10% by weight para-toluene sulfonic acid in dimethyl sulfoxide.
