Abstract

Monoorgano tin trialkoxide compounds having chemical formula R′SnX3 and containing less than about 5 mol % R′2SnX2 are described. R′ is an optionally substituted organic substituent having about 1 to about 20 carbon atoms and each X is independently ORf, wherein Rf is a fluorinated organic substituent having about 1 to about 20 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.
