Patent ID: 8263312

Claim:
A method of forming an antireflective coating (ARC) on an electronic device comprising (A) applying to an electronic device an ARC composition comprising (i) a silsesquioxane resin having the formula (PhSiO (3-x)/2 (OH) x ) m HSiO (3-x)/2 (OH) x ) n (MeSiO (3-x)/2 (OH) x ) p where Ph is a phenyl group, Me is a methyl group, x has a value of 0, 1 or 2; m has a value of 0.01 to 0.99, n has a value of 0.01 to 0.99, p has a value of 0.01 to 0.99, and m+n+p≈1; (ii) a polyethylene oxide fluid having the general formula R 1 (CH 2 CH 2 O) z R 2 , wherein R 1 is allyl and R 2 is selected from H, a hydrocarbon group having 1 to 3 carbon atoms, an unsaturated hydrocarbon group, and an acetyl group (CH 3 CO—), and z is such that the polyethylene oxide fluid typically has a molecular weight of 50 to 5000 g/mol; and (iii) a solvent; and (B) removing the solvent and curing the silsesquioxane resin to form an ARC on the electronic device.
