    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 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 with UV and EUV light is described with organo tin sulfide (and selenide) clusters. The clusters are solids at room temperature and are soluble in organic solvents that are not too polar. Irradiation can either fragment a carbon metal bond or crosslink unsaturated organic moieties to stabilize the irradiated material. The irradiated material then resists dissolving in organic solvents so that the un-irradiated material can be contacted with an organic solvent to develop the latent image formed with the radiation. Radiation patternable layers can be formed through coating a solution or through vapor deposition. Corresponding precursor solutions, structures and methods are described.
