Abstract: The present invention discloses an antireflective coating composition for applying between a substrate surface and a positive photoresist composition. The antireflective coating composition is developable in an aqueous alkaline developer. The antireflective coating composition comprises a polymer, which comprises at least one monomer unit containing one or more moieties selected from the group consisting of a lactone, maleimide, and an N-alkyl maleimide; and at least one monomer unit containing one or more absorbing moieties. The polymer does not comprise an acid labile group. The present invention also discloses a method of forming and transferring a relief image by using the inventive antireflective coating composition in photolithography.
