摘要： Disclosed is a novel and improved photoresist composition which comprises: (A) a film-forming resinous compound which is, in the presence of an acid, subject to a change in the solubility in an alkaline solution; and (B) an acid-generating agent capable of releasing an acid by the exposure to actinic rays which is an oxime sulfonate compound represented by the general formula NC--CR.sup.1 .dbd.N--O--SO.sub.2 --R.sup.2, in which R.sup.1 and R.sup.2 are, each independently from the other, an unsubstituted or halogen-substituted monovalent aliphatic hydrocarbon group, e.g., alkyl, cycloalkyl, alkenyl and cycloalkenyl groups. By virtue of the non-aromatic nature of the component (B) as well as good solubility thereof in organic solvents and high acid strength of the acid released therefrom, the composition is highly transparent to deep ultraviolet light even when the content of the component (B) is relatively large and the photosensitivity of the composition is very high so that the photoresist composition is capable of giving a patterned resist layer having excellent characteristics.

摘要： Disclosed is a class of novel cyanooxime sulfonate compounds represented by the general formula NC--CR.sup.1 .dbd.N--O--SO.sub.2 --R.sup.2, in which R.sup.1 and R.sup.2 are, each independently from the other, an unsubstituted or halogen-substituted monovalent aliphatic hydrocarbon group selected from the group consisting of alkyl, cycloalkyl, alkenyl and cycloalkenyl groups. The group R.sup.1 is preferably a cycloalkenyl group, e.g. 1-cyclopentenyl or 1-cyclohexenyl group, and R.sup.2 is preferably a lower alkyl group having 1 to 4 carbon atoms. The compound releases an acid by the irradiation with ultraviolet light and is useful as an acid generating agent in an acid-sensitive photoresist composition. By virtue of the high transparency of the compound to ultraviolet, high acid strength of the acid generated therefrom and good solubility of the compound in organic solvents, the photoresist composition compounded with the compound as an acid generating agent is imparted with high sensitivity to ultraviolet and capable of giving a patterned resist layer having excellent characteristics.
