Document Type and Number:
Japanese Patent JP2020152720
Kind Code:
A
Abstract:
To provide a carboxylate that makes it possible to produce a resist pattern having excellent line edge roughness, and a resist composition containing the same.SOLUTION: The present invention provides a carboxylate represented by formula (I), a carboxylic acid generator and a resist composition containing the same. [In formula (I), R1 is a C1-12 fluorinated alkyl group. R2 and R3 independently represent a halogen atom, a C1-12 fluorinated alkyl group or a C1-12 alkyl group, where -CH2- contained in the alkyl group is optionally substituted with -O- or -CO-. m2 is an integer of 0-4. m3 is an integer of 0-4. X0 is an optionally substituted C1-72 hydrocarbon group. -CH2- contained in the hydrocarbon group is optionally substituted with -O-, -S-, -CO- or -SO2-.]SELECTED DRAWING: None
