摘要： A photoacid generator (PAG) and a photoresist composition, the PAG being represented by the following Chemical Formula (I): wherein, in Chemical Formula (I), L is sulfur (S) or iodine (I), R3 being omitted when L is I; R1, R2, and R3 are each independently a C1 to C10 alkyl, alkenyl, alkynyl, or alkoxy group that is unsubstituted or substituted with a heteroatom such that the heteroatom is pendant or is between the group and L, or a C6 to C18 aryl, arylalkyl, or alkylaryl group that is unsubstituted or substituted with a heteroatom such that the heteroatom is pendant or is between the group and L; AL is an acid-labile group; m is 1 to 4; and M is a C1 to C30 hydrocarbon group that is unsubstituted or substituted with a heteroatom such that the heteroatom is pendant or is between the group and a sulfur atom.
