Latest Patents

Caroff holds a patent for "High purity tin compounds containing unsaturated substituent and method for preparation thereof." This patent describes monoorgano tin trialkoxide compounds with the chemical formula R'Sn(OR), which contain less than about 5 mol % diorgano tin dialkoxide. The compounds feature R′ as a linear or branched, optionally fluorinated, unsaturated hydrocarbon group with about 2 to about 20 carbon atoms, while each R is a linear or branched, optionally fluorinated, alkyl group with about 1 to about 10 carbon atoms. The methods for synthesizing and purifying these compounds are also detailed in the patent. These monoorgano tin compounds are particularly useful for forming high-resolution EUV lithography patterning precursors due to their high purity and minimal concentration of diorgano tin impurities.
