摘要： A negative photoresist stripping liquid composition is provided which comprises from 30 to 75% by weight of dimethyl sulfoxide, from 20 to 65% by weight of 1,3-dimethyl-2-imidazolidinone, from 0.1 to 5% by weight of a tetraalkylammonium hydroxide and from 0.5 to 15% by weight of water. The composition has a superior stripping performance especially against photoresists that are alkali-developable and can form films of at least 20 .mu.m in thickness, and has no problem of freezing even when stored outdoors in the winter. The composition is useful for the stripping of negative photoresists for bump formation and for fabricating circuit substrates.
