Abstract:
A pure composition comprises a monoalkyltin trialkoxide compound represented by the chemical formula RSn(OR′) 3  or a monoalkyl tin triamide compound represented by the chemical formula RSn(NR′ 2 ) 3  and no more than 4 mole % dialkyltin compounds relative to the total tin amount, where R is a hydrocarbyl group with 1-31 carbon atoms, and wherein R′ is a hydrocarbyl group with 1-10 carbon atoms. Methods are described for the formation of the pure compositions. A solid composition comprises a monoalkyl triamido tin compound represented by the chemical formula RSn—(NR′COR″) 3 , where R is a hydrocarbyl group with 1-31 carbon atoms, and where R′ and R″ are independently a hydrocarbyl group with 1-10 carbon atoms. The compositions are suitable for the formation of resist compositions suitable for EUV patterning in which the compositions have a high EUV absorption.

Claim (Index 9):
A method to selectively form a monoalkyltin trialkoxide compound with low dialkyl tin contamination, the method comprising,\n reacting RSn(NR\u2032 2 ) 3  with an alcohol represented by the formula HOR\u2033 in an organic solvent to form RSnOR\u2033 3 , wherein the RSn(NR\u2032 2 ) 3  reactant has no more than about 4 mole % dialkyl tin contaminants and is the product of the method of  claim 1 , wherein R is a hydrocarbyl group with 1-31 carbon atoms, and wherein R\u2032 and R\u2033 are independently a hydrocarbyl group with 1-10 carbon atoms.
