Abstract
A chemical amplified photoresist composition containing a resin, an acid generator, and a compound of formula (X): wherein R, R, R, R, Rand Reach independently represent a hydrogen atom, a hydroxyl group, a carboxy group, —SO, —NH, a halogen atom, a mercapto group, a C1-C12 alkyl group optionally having a substituent, a C6-C30 aryl group optionally having a substituent, a C3-C12 cycloalkyl group optionally having a substituent, and Rand Reach independently represent a hydrogen atom, a hydroxyl group, a carboxy group, —SO, —NH, a halogen atom, a mercapto group, a C1-C12 alkyl group optionally having a substituent, a C6-C30 aryl group optionally having a substituent, or a C3-C12 cycloalkyl group optionally having a substituent, or Rand Rare bonded each other to form a ring together with carbon atoms binding Rand Rand with the carbon atoms forming the bond between the pyridine rings.
