Salt suitable for an acid generator and a chemically amplified resist composition containing the same |
摘要 |
The present invention provides a salt of the formula (I): wherein ring Y represents monocyclic or polycyclic hydrocarbon group having 3 to 30 carbon atoms, in which one -CH<SUB>2</SUB>- group is substituted with -COO- group, and at least one hydrogen atom in the monocyclic or polycyclic hydrocarbon group may optionally be substituted with alkyl group having 1 to 6 carbon atom, alkoxy group having 1 to 6 carbon atom, perfluoroalkyl group having 1 to 4 carbon atoms, hydroxyalkyl group having 1 to 6 carbon atoms, hydroxyl group or cyano group; Q<SUP>1 </SUP>and Q<SUP>2 </SUP>each independently represent fluorine atom or perfluoroalkyl group having 1 to 6 carbon atoms; A<SUP>+</SUP> represents organic counter ion; and n shows an integer of 0 to 12. The present invention also provides a chemically amplified resist composition comprising the salt of the formula (I).
