Patent ID: 7718344

Claim:
A resist composition, comprising: (B) a polymer having a group capable of decomposing under an action of an acid and having a weight average molecular weight of 1,000 to 5,000, of which solubility in an alkali developer increases under an action of an acid; (Z) a compound containing a sulfonium cation having a structure represented by formula (Z-I): wherein Y 1 to Y 13 each independently represents a hydrogen atom or a substituent, and adjacent members of Y 1 to Y 13 may combine with each other to form a ring, Z represents a single bond or a divalent linking group; and (A) a compound capable of generating a compound having a structure represented by the following formula (A-I) upon irradiation with actinic rays or radiation: Q 1 -X 1 —NH—X 2 -Q 2 (A-I) wherein Q 1 and Q 2 each independently represents a monovalent organic group, provided that at least one of Q 1 and Q 2 has a proton acceptor functional group, Q 1 and Q 2 may combine to form a ring and the ring formed may have a proton acceptor functional group; and X 1 and X 2 each independently represents —CO— or —SO 2 —.
