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.

Abstract: Patterning compositions are described based on organo tin dodecamers with hydrocarbyl ligands, oxo ligands, hydroxo ligands and carboxylato ligands. Alternative dodecamer embodiments have organo tin ligands in place of hydrocarbyl ligands. The organo tin ligands can be incorporated into the dodecamers from a monomer with the structure (RCC)3SnQ, where R is a hydrocarbyl group and Q is a alkyl tin moiety with a carbon bonded to the Sn atom of the monomer and with a Sn bonded as a replacement of a quaternary carbon atom with bonds to 4 carbon atoms. Some or all of the carboxylato and hydroxyl ligands can be replaced with fluoride ions. Good EUV patterning results are obtained with the dodecamer based patterning compositions.
