Patent ID: 8268397

Claim:
A method of forming a thin film on a substrate, comprising: providing an organometallic precursor onto the substrate, the organometallic precursor including a central metal, a borohydride ligand coordinating to the central metal, and an amine ligand coordinating to the central metal and reducing a polarity of the organometallic precursor; and decomposing the organometallic precursor to form the thin film on the substrate, wherein the organometallic precursor comprises a compound having a chemical structure represented by Formula 1, wherein R 1 and R 2 are each independently C 1 -C 4 alkyl, R 3 , R 4 , and R 5 are each independently hydrogen, C 1 -C 10 alkyl, cycloalkyl or aryl, provided that compounds wherein all of R 3 , R 4 , and R 5 are hydrogen, methyl, or a combination of hydrogen and methyl are excluded.
