摘要:
There is provided a positive resist composition, including a base component (A) which exhibits increased solubility in an alkali developing solution under action of an acid, and an acid generator component (B) which generates an acid upon exposure, wherein the base component (A) includes a polymeric compound (A1) containing a structural unit (a0) represented by the general formula (a0-1) shown below:
wherein R 1 represents a hydrogen atom, a lower alkyl group or a halogenated lower alkyl group; A represents a bivalent linking group; B represents a bivalent linking group; and R 2 represents an acid dissociable, dissolution inhibiting group.
摘要(中):
