Abstract:
A positive-working chemical-sensitization photoresist composition which comprises, in the form of a uniform solution in an organic solvent:(a1) 100 parts by weight of an alkali-soluble hydroxy group-containing resin, of which at least a part of the hydroxy groups are substituted each by an acid-dissociable substituent group and the ratio of the weight-average molecular weight to the number-average molecular weight Mw:Mn does not exceed 3.5; and(b) from 0.1 to 30 parts by weight of a cyano group-containing oximesulfonate compound, as an acid-generating agent, represented by the general formulaR.sup.1 --C(CN)=N--O--SO.sub.2 --R.sup.2,in which R.sup.1 is an aromatic monovalent group and R.sup.2 is an alkyl group having 1 to 4 carbon atoms unsubstituted or substituted by halogen atoms.
