Patent ID: 7431858

Claim:
A microlithographic arrangement comprising a) a microstructured layer of a nanocomposite composition comprising a1) a polymerizable silane of the general formula (I) and/or (II) and/or condensates derived therefrom SiX 4 (I) in which the radicals X are identical or different and are hydrolyzable groups or hydroxyl groups; R 1 a R 2 b SiX (4-a-b) (II) in which R 1 is a nonhydrolyzable radical, R 2 is a radical carrying a functional group, X has the above meaning and a and b have the value 0, 1, 2 or 3, the sum (a+b) having the value 1, 2 or 3, and a2) nanoscale particles selected from the group consisting of the oxides, sulfides, selenides, tellurides, halides, carbides, arsenides, antimonides, nitrides, phosphides, carbonates, carboxylates, phosphates, sulfates, silicates, titanates, zirconates, aluminates, stannates, plumbates and mixed oxides thereof, as a top coat; b) a bottom coat comprising an aromatics-containing polymer or copolymer containing novolaks, styrenes, (poly)hydroxystyrenes and/or (meth)acrylates; c) a substrate.
