Abstract:
A radiation-sensitive composition consisting essentially of:an acid-generating compound capable of generating an acid upon exposure to radiation and represented by the formula (I): ##STR5## wherein X, Y and R.sup.1 to R.sup.5 have the following meanings: X and Y: independently a direct bond, C.sub.1 -C.sub.18 alkylene, C.sub.1 -C.sub.4 alkene, --O--R.sup.11 --O-- (wherein R.sup.11 is an alkylene group having 1 to 4 carbon atoms), --NH--, --O--, --S--, --SO.sub.2 --, --CO--, --COO-- or --CONR.sup.12 -- (wherein R.sup.12 is a hydrogen atom, C.sub.1 -C.sub.18 is alkyl, alkylaryl, halogenated alkyl, halogenated aryl, a halogen atom, alkoxy, phenoxy, alkylsulfonyl-oxy, halogenated alkylsulfonyl-oxy, or substituted or unsubstituted arylsulfonyl-oxy);R.sup.1 to R.sup.4 : a hydrogen atom, C.sub.1 -C.sub.18 alkyl, aryl, hetero-aryl, a halogen atom, amino which may be substituted by an alkyl or aryl, amide which may be substituted by alkyl or aryl, nitro, cyano, aldehyde, acetal, alkoxy, phenoxy, alkylsulfonyl-oxy, or substituted or unsubstituted arylsulfonyl-oxy;R.sup.5 : a hydrogen atom, alkyl, aryl, halogenated alkyl, halogenated aryl, halogenated hetero-aryl, alkylsulfonyl-oxy, halogenated alkylsulfonyl-oxy, or substituted or unsubstituted arylsulfonyl-oxy;a water-insoluble but aqueous alkaline solution-soluble binder comprising (i) novolak resins for X-ray or electron beam sensitive compositions or (ii) a water-insoluble but alkaline solution-soluble binder comprising a homopolymer or copolymer of p-hydroxystyrene or p-hydroxystyrene with one or more alkyl substituents on its benzene ring for deep UV sensitive compositions; anda cross-linking compound capable of reacting with said binder in the presence of said acid to cause the binder to be cross-linked.
