RESIST COMPOSITION, METHOD OF FORMING RESIST PATTERN, POLYMERIC COMPOUND AND COMPOUND |
摘要 |
A resist composition which generates acid upon exposure and exhibits changed solubility in a developing solution under action of acid, including a base component (A) which exhibits changed solubility in a developing solution under action of acid, the base component (A) including a polymeric compound (A1) containing a structural unit (a0) represented by general formula (a0-1) shown below. In the formula, W1 represents a group which is formed by polymerization reaction of a group containing a polymerizable group; Y1 and Y2 each independently represents a divalent linking group; Y3 represents a carbonyl group or an alkylene group; R2 and R3 each independently represents a fluorine atom or a fluorinated alkyl group; Mm+ represents an organic cation having a valency of m; and m represents an integer of 1 or more.; |

1. A resist composition which generates acid upon exposure and exhibits changed solubility in a developing solution by the action of acid, comprising:
a base component (A) which exhibits changed solubility in a developing solution by the action of acid, the base component (A) comprising a polymeric compound (A1) comprising a structural unit (a0) represented by general formula (a0-1) shown below: wherein W1 represents a group which is formed by polymerization reaction of a group containing a polymerizable group; Y1 and Y2 each independently represents a divalent linking group; Y3 represents a carbonyl group or an alkylene group; R2 and R3 each independently represents a fluorine atom or a fluorinated alkyl group; Mm+ represents an organic cation having a valency of m; and m represents an integer of 1 or more. |
