    摘要: The present invention relates to an antireflective coating composition comprising a novel polymer without an aromatic chromophore, where the polymer comprises a structural unit derived from an aminoplast and a structural unit derived from a diol, triol, dithiol, trithiol, other polyols, diacid, triacid, other polyacids, diimide or mixture thereof, where the diol, dithiol, triol, trithiol, diacid, triacid, diimide, diamide or imide-amide optionally contain one or more nitrogen and/or sulfur atoms or contain one or more alkene groups. The invention also relates to the novel polymer and a process for using the novel antireflective coating composition in a lithographic process.
