Patent ID: 7659352

Claim:
An antireflective coating composition, comprising, as a uniform solution in an organic solvent: an initiator; a polymerizable oxide-containing colloid, comprising condensation products derived from (i) colloid particles having a formula (I), of Z x O y , and (ii) a compound with polymerizable groups having a formula (II), of (R 1 ) n —M(OR 2 ) m , wherein Z is element of Group IIIB, Group IVB, or Group VB, W, Be, Ti, Zr, or Zn; x and y are integers equal to or more than 1; R 1 is acryloyl group, epoxy group, or isocyanato group; R 2 is alkyl group or haloalkyl group; M is Si, Al, Ti, Zr, Sn, or Sb; and n and m are integers equal to or more than 1, wherein the weight ratio between (i) the colloid particles and (ii) the compound with polymerizable groups is 10:1˜1:10; and a template, wherein the weight ratio between the template and the polymerizable oxide-containing colloid is 45:55˜5:95, and the template comprises a polymer non-reactive with polymerizable oxide-containing colloid.
