Provided is a thermal acid generator of formula (1) below. In formula (1), Ar^1 represents an optionally substituted carbocyclic or heterocyclic aromatic group; W independently represents a group selected from carboxyl, hydroxy, nitro, cyano, C1-5 alkoxy, and formyl groups; X is a cation; Y independently represents a linking group; Z independently represents a group selected from hydroxyl, fluorinated alcohol, ester, optionally substituted alkyl, optionally substituted monocyclic of C5 or more, polycyclic, fused polycyclic alicyclic, and aryl which can optionally contain hetero-atoms but, in at least one case, Z is a hydroxyl group; a is an integer of 0 or greater; and b is an integer of 1 or greater. Meanwhile, a + b is at least 1 and not more than the total number of available aromatic carbon atoms of an aromatic group. In addition, provided is a photoresist pattern trimming composition and a method for trimming a photo resist pattern by using the same. According to the present invention ...
