Abstract:
The present invention relates to an antireflective coating composition comprising a crosslinking agent, a polymer comprising at least one chromophore group and at least one hydroxyl and/or a carboxyl group, and an additive, further where the additive has structure 1 and comprises at least one arylene-hydroxyl moiety, where Y is selected from an carboxylate anion or sulfonate anion, R1, R2, and R3 are independently selected from unsubstituted C1-C8 alkyl, substituted C1-C8 alkyl, aryl and arylene-hydroxyl; X1, X2, and X3 are independently selected from direct valence bond and C1-C8 alkylene group, and, n=1, 2 or 3. The invention further relates to a process for using the composition.
