Abstract:
1. A top antireflective coating and barrier layer material for applying on top of a photoresist material comprising a polymer having at least one hydrophobic moiety comprising a monomer unit of monomer structure (I) or (II): wherein M is a polymerizable backbone moiety, Z of monomer structure (I) or (II) is a linkage moiety selected from the group consisting of —C(O)O—, —C(O)—, —OC(O)—, and —O—C(O)—C(O)—O—, R at least one acidic moiety with a pKa of 1 or less, wherein the at least one acidic moiety with a pKa of 1 or less comprises a monomer unit having the following monomer structure: wherein M is a polymerizable backbone moiety; Q of monomer structure (XVIII) is a linkage moiety selected from the group consisting of —OC(O)—, —C(O)NH— and —NHC(O)—, R at least one aqueous base soluble moiety, wherein the at least one aqueous base soluble moiety comprises a monomer unit with a monomer selected from the group consisting of: wherein m is an integer of 1 to 19.
