Patent ID: 8841060

Claim:
An actinic-ray-sensitive or radiation-sensitive resin composition comprising: (A) a resin having at least a repeating unit having a structure represented by any one of the following general formulae (I-1) to (I-3), and at least a repeating unit having a group containing a lactone structure, a sultone structure, or a cyano group; and (B) a compound that generates an acid by irradiation with actinic rays or radiation: wherein in the general formulae above, R 11 , R 12 , and R 13 each independently represents a monovalent organic group, when a plurality of R 11 's, R 12 's, or R 13 's are each present, the plurality of R 11 's, R 12 's, or R 13 's may be the same as or different from each other and may be linked to each other to form a ring, Ra 1 , Ra 2 , and Ra 3 each independently represents an alkyl group or a cycloalkyl group, X 1 , X 2 , and X 3 each independently represents an oxygen atom or a sulfur atom, Z 11 , Z 12 , and Z 13 each independently represent a single bond or a divalent linking group, * represents a moiety linked to a resin, l I-1 represents an integer number of 0 to 12, l I-2 represents an integer number of 0 to 10, and l I-3 represents an integer number of 0 to 12, m I-1 represents an integer number of 1 to 3 and n I-1 represents an integer number of 1 to 3, provided that m I-1 +n I-1 is equal to 2 to 4, and m I-3 represents an integer number of 1 to 5 and n I-3 represents an integer number of 1 to 5, provided that m I-3 +n I-3 is equal to 3 to 6.
