12. A radiation-sensitive resin composition comprising (A) an acid-labile group-containing resin having a structure represented by the following formula (1); (B) a photoacid generator; and (C) a nitrogen containing organic compound as an acid diffusion controller:
chemical complex work unit
wherein R1 represents a hydrogen atom, a monovalent acid-labile group, an alkyl group having 1-6 carbon atoms which does not have an acid-labile group, or an alkylcarbonyl group having 2-7 carbon atoms which does not have an acid-labile group, X1 represents a linear or branched fluorinated alkyl group having 1-4 carbon atoms, and R2 represents a hydrogen atom, a linear or branched alkyl group having 1-10 carbon atoms, or a linear or branched fluorinated alkyl group having 1-10 carbon atoms and wherein the nitrogen-containing organic compound selected from the group consisting of a compound shown by the following formula (10), a compound having two nitrogen atoms in the molecule, a polyamino compound or polymer having three or more nitrogen atoms, a quarternary ammonium hydroxide compound, an amide group-containing compound, a urea compound, and a nitrogen-containing heterocyclic compound:
chemical complex work unit
wherein R12 individually represents a hydrogen atom, a substituted or unsubstituted, linear, branched, or cyclic alkyl group, substituted or unsubstituted aryl group, or substituted or unsubstituted aralkyl group.
