Salt and photoresist composition comprising the same |
摘要 |
A salt represented by the formula (I):;wherein R1 and R2 independently each represent a hydrogen atom, a hydroxy group or a C1-C12 hydrocarbon group where a methylene group can be replaced by an oxygen atom or a carbonyl group;Ar represents a C6-C36 aromatic hydrocarbon group which can have a substituent or a C6-C36 heteroaromatic hydrocarbon group which can have a substituent;A− represents an organic anion; and“m” and “n” independently each represent an integer of 1 or 2. |

1. A salt represented by the formula (I): wherein R1 and R2 independently each represent a hydrogen atom, a hydroxy group or a C1-C12 hydrocarbon group where a methylene group can be replaced by an oxygen atom or a carbonyl group; Ar represents a phenyl group which can have a substituent; A− represents an organic anion of formula (I-A): wherein Q1 and Q2 independently each represent a fluorine atom or a C1-C6 perfluoroalkyl group; Lb1 represents a C1-C24 divalent saturated hydrocarbon group where a methylene group can be replaced by an oxygen atom or a carbonyl group and where a hydrogen atom can be replaced by a fluorine atom or a hydroxyl group; and Y represents a methyl group or a C3-C18 alicyclic hydrocarbon group where a methylene group can be replaced by an oxygen atom, a carbonyl group or a sulfonyl group and where a hydrogen atom can be replaced by a substituent; and “m” and “n” independently each represent an integer of 1 or 2. |
