    • The invention relates to an antireflective coating composition for a photoresist layer comprising a polymer, a crosslinking agent and an acid generator, where the polymer comprises at least one unit of structure 1, where, X is a linking moiety selected from a nonaromatic (A) moiety, aromatic (P) moiety and mixture thereof, R′ is a group of structure (2), R″ is independently selected from hydrogen, a moiety of structure (2), Z and W—OH, where Z is a (C1-C20) hydrocarbyl moiety and W is a (C1-C20) hydrocarbylene linking moiety, and, Y′ is independently a (C1-C20) hydrocarbylene linking moiety, where structure (2) is where R1 and R2 are independently selected from H and C1-C4alkyl and L is an organic hydrocarbyl group. The invention further relates to a process for imaging the antireflective coating composition.
