Claim 11:
12. A method for patterning a radiation sensitive coating, the method comprising:
forming a coating on a substrate surface with an organotin precursor solution wherein the organotin precursor solution has a uniform composition resulting from adjusting the water content of the solvent used to form the organotin precursor solution within about ±15% of a selected water content, wherein the selected water content is from about 250 ppm by weight to about 10,000 ppm by weight, and wherein the organotin precursor solution comprises a mixture of alcohol with the selected water content and a first monoalkyl tin trialkoxide (RSn(OR′)3), wherein R and R′ are independently hydrocarbyl groups having from 1-31carbon atoms with one or more carbon atoms optionally substituted with one of more heteroatom functional groups, wherein the organotin precursor solution has a tin concentration from about 0.004M to about 1.0M;
drying the coating; and
irradiating the dried coating to form a latent image.
