Abstract: Precursors and methods related to a tin-based photoresist are disclosed herein. In some embodiments, a method for forming a tin-based photoresist may include exposing a tin-containing precursor and a co-reagent to a substrate to form a photoresist having tin clusters; selectively exposing the photoresist to extreme ultraviolet radiation (EUV); and exposing the photoresist to heat to form, in the region, crosslinking between the tin clusters. In some embodiments, the precursor has a formula R1R2Sn(N(CH3)2)2, and R1 and R2 are selected from the group consisting of neo-silyl, neo-pentyl, phenyl, benzyl, methyl-bis(trimethylsilyl), methyl, ethyl, isopropyl, tert-butyl, n-butyl, N,N-dimethylpropylamine, and N, N-dimethlybutylamine. In other embodiments, the precursor includes a chelating alkyl-amine or alkyl-amide ligand featuring a 5 membered or 6 membered tin-based heterocycle bound ?2-C,N with an alkyl group on the ligand backbone, wherein the alkyl group includes methyl, ethyl, vinyl, hydrogen, or tert-butyl.
