A method of forming an antireflective coating 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)mHSiO(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 0.05 to 0.95, n has a value of 0.05 to 0.95, p has a value of 0.05 to 0.95, and m + n + p ≈ 1; and (ii) a solvent; and (B) removing the solvent and curing the silsesquioxane resin to form an antireflective coating on the electronic device. |
