Patent ID: 8404426

Claim:
A negative resist composition comprising an alkali-soluble resin component (A), an acid generator component (B) that generates acid upon exposure, and a cross-linking component (C), said alkali-soluble resin component (A) comprising a polymeric compound (F) having a structural unit (f1) represented by general formula (f1-1) or (f1-2) shown below and a structural unit (f2) containing a cross-linking group-containing group: wherein each R independently represents a hydrogen atom, a lower alkyl group or 1 to 5 carbon atoms or a halogenated lower alkyl group of 1 to 5 carbon atoms; X represents a divalent organic group; A aryl represents an aromatic cyclic group which may have a substituent: X 01 represents a single bond —O—, —C(═O), —C(═O)—O—, (—O—C(═O)—O—), —NH—C(═O)—, a combination thereof, or a combination thereof having an alkylene group of 1 to 10 carbon atoms; and each R 2 independently represents an organic group having a fluorine atom.
