Abstract: Organotin patterning compositions have radiation sensitive ligands with acetal functional groups. Precursor compositions are compositions comprising (OR4)(OR3)R2CR1SnL3, where the R groups are substituted or unsubstituted hydrocarbyl groups and L is a hydrolysable ligand. The precursors can be formed into coating that can be patterned with radiation, in particular EUV radiation. Coatings formed with blended precursors with hydrocarbyl-based ligands with some having acetal groups and others lacking acetal groups can be particularly effective for improving positive tone patterning.
