SALT AND PHOTORESIST COMPOSITION COMPRISING THE SAME

摘要

The present invention relates to a salt and a photoresist composition including the salt. Particularly, a salt is represented by chemical formula (I): [Chemical Formula 1] In the chemical formula 1, R^1 and R^2 independently 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 to 2.
