Abstract:
A method for roughening a surface of a substrate, including: applying a composition containing inorganic particles and organic resin to the surface of the substrate and drying and curing the composition to form an organic resin layer; and etching the substrate by a solution containing hydrogen fluoride, hydrogen peroxide, or an acid, to roughen the surface. Preferably, the solution contains hydrogen fluoride and ammonium fluoride or hydrogen peroxide and ammonia, the resin layer contains a ratio of the particles to the resin of 5 to 50 parts by mass to 100 parts by mass, and the composition is a mixture of silica sol wherein silica is dispersed as the inorganic particles in organic solvent or titanium oxide sol wherein titanium oxide is dispersed, with a solution of the organic resin. The method is applied to a light extraction layer of an LED or a low-reflective glass of a solar cell.

Claim (Index 14):
The method for roughening a surface according to  claim 10 , wherein one or both of the compositions (a3) and (b3) further contains a crosslinker and a cross-linking catalyst.
