Patent ID: 7226640

Claim:
A method of forming an iridium-containing film on a substrate, comprising use of an organic solvent solution, said organic solvent solution comprising an iridium-containing precursor that is decomposable to deposit iridium on the substrate, said method comprising decomposing the precursor from said solution and depositing iridium on the substrate in an oxidizing ambient environment, wherein the precursor comprises a composition selected from the group consisting of: Lewis base stabilized Ir(I) β-diketonates of formula I: wherein R and R′ may be alike or different and may be H, aryl, perfluoroaryl, C 1 –C 6 alkyl, or C 1 –C 6 perfluoroalkyl, and L is a coordinating Lewis base; and Lewis base stabilized Ir(I) β-ketoiminates of formula II: wherein R, R′, and R″ are the same or different, and are independently selected from the group consisting of H, aryl, perfluoroaryl, C 1 –C 6 alkyl, or C 1 –C 6 perfluoroalkyl, and L is a coordinating Lewis base.
