Zusammenfassung:A chemically modified anti-reflective (AR) coating is provided having improved durability. The AR coating may be a polymerized alkoxy siloxane-based material that includes a densifier in the form of an organic or inorganic phosphorus (P)-based compound, boron (B)-based compound, antimony (Sb)-based compound, bismuth (Bi)-based compound, lead (Pb)-based compound, arsenic (As)-based compound, or combinations thereof. At least one residue of the densifier may be chemically and/or physically incorporated into the polymerized alkoxy siloxane-based material.
