Patent ID: 7851129

Claim:
A resist composition comprising a base material component (A) having an acid dissociable dissolution inhibiting group in which alkali solubility enhances under an action of an acid, and an acid generator component (B) which generates an acid upon exposure, wherein the base material component (A) contains a compound (A1) in which a portion or all of hydrogen atoms of phenolic hydroxyl groups in a polyhydric phenol compound (a) having two or more phenolic hydroxyl groups and having a molecular weight of 300 to 2,500 are substituted with at least one selected from the group consisting of acid dissociable dissolution inhibiting groups represented by the following general formulas (p1) and (p2): wherein R 1 and R 2 each independently represents a branched or cyclic alkyl group, and may contain a hetero atom in the structure; R 3 represents a hydrogen atom or a lower alkyl group; and n′ represents an integer of 1 to 3, wherein the proportion of the compound (A1) within the component (A) is within a range from greater than 80 wt % to 100 wt %.
