Claim Text:
1. A method for patterning a substrate with radiation, the method comprising: irradiating a coated substrate along a selected pattern to form an irradiated structure with a region of irradiated coating and a region with un-irradiated coating, wherein the coated substrate comprises a coating having an average thickness from about 5 nm to about 200 nm and that comprises a metal oxo-hydroxo network with organic ligands with metal carbon bonds and/or with metal carboxylate bonds and free of peroxide ligands; heating the irradiated structure at a temperature from about 45° C. to about 250° C. for 0.1 minutes to about 30 minutes to form an annealed irradiated structure; and selectively developing the annealed irradiated structure to remove a substantial portion of the irradiated coating or of the un-irradiated coating to form a patterned substrate wherein the metal oxo-hydroxo network comprises both M-O—H linkages and M-O-M linkages.
