    摘要: Organic coating composition are provided including antireflective coating compositions that can reduce reflection of exposing radiation from a substrate back into an overcoated photoresist layer and/or function as a planarizing or via-fill layer. Preferred compositions of the invention comprise contain a crosslinker component that is resistant to sublimination or other migration crosslinker from the composition coating layer during lithographic processing.

    摘要: The invention is for a process of removal of dissolved cation contaminants from a resin solution. The process of the invention involves providing a chelating ion exchange resin modified by treatment with an acid and contact of said solution with said modified exchange resin for a time sufficient to remove ionic metal impurities. The invention is useful for removal of ionic contaminants from resin solutions used in the preparation of photoresists.
