Abstract

Monoorgano tin trialkoxide compounds having chemical formula R′Sn(OR)3 and containing less than about 5 mol % diorgano tin dialkoxide are described. R′ is a linear or branched, optionally fluorinated, unsaturated hydrocarbon group having about 2 to about 20 carbon atoms and each R is independently a linear or branched, optionally fluorinated, alkyl group having about 1 to about 10 carbon atoms. Methods for synthesizing and purifying these compounds are also provided. The monoorgano tin compounds may be used for the formation of high-resolution EUV lithography patterning precursors and are attractive due to their high purity and minimal concentration of diorgano tin impurities.
