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 12):
The method of  claim 11  wherein the monoalkyl tin triamide is at an initial concentration from about 0.1M to about 8M and wherein the solvent is an alkane, an aromatic hydrocarbon, or an ether.
