ABSTRACT:
The present invention relates to an antireflective coating composition comprising, (i) a thermal acid generator; (ii) a crosslinkable polymer comprising at least one aromatic group; and, (iii) a polymeric crosslinker comprising at least one unit of structure (6),where R11to R13is independently selected from H, (C1-C6) alkyl and aromatic group, R14and R15are independently (C1-C10) alkyl. The invention also relates to a process for imaging the antireflective coating composition of the present invention.
