    Abstract: A photoresist underlayer composition comprising a poly(arylene ether); an additive of formula (14): D-(L1-Ar—[X]n)m  (14); and a solvent, wherein, in formula (14), D is a substituted or unsubstituted C1-60 organic group, optionally wherein D is an organic acid salt of the substituted or unsubstituted C1-60 organic group; each L1 is independently a single bond or a divalent linking group, when L1 is a single bond, D may be a substituted or unsubstituted C3-30 cycloalkyl or substituted or unsubstituted C1-20 heterocycloalkyl that is optionally fused with Ar, each Ar is independently a monocyclic or polycyclic C5-60 aromatic group, each X is independently —OR30, —SR31, or —NR32R33, m is an integer of 1 to 6, each n is independently an integer of 0 to 5, provided that a sum of all n is 2 or greater, and R30 to R33 are as provided herein.

    Abstract: Photoresist compositions comprise: an acid-sensitive polymer comprising a first repeating unit formed from a first free radical polymerizable monomer comprising an acid-decomposable group and a second repeating unit formed from a second free radical polymerizable monomer comprising a carboxylic acid group; a compound comprising two or more enol ether groups, wherein the compound is different from the acid-sensitive polymer; a material comprising a base-labile group; a photoacid generator; and a solvent. The photoresist compositions and pattern formation methods using the photoresist compositions find particular use in the formation of fine lithographic patterns in the semiconductor manufacturing industry.
