Patent ID: 7250379

Claim:
A method of forming a metal oxide comprising: introducing an organic metal compound represented by the following chemical formula into a chamber to chemisorb the organic metal compound onto a substrate, M[L1]x[L2]y wherein, M represents a metal, L1 and L2 respectively represent a first and second ligands, the first and second ligands independently include at least one ligand selected from the group consisting of a halide ligand, a diketonate ligand, an alkoxide ligand, an amino ligand, an alkoxyamine ligand, an amidinate ligand, and a multidentate ligand including at least two electron pair donors, L1 and L2 are substantially different from each other, and x and y are independently integers such that a value of (x+y) is an integer ranging from 3 to 5; removing a non-chemisorbed organic metal compound from the chamber; and introducing an oxygen-containing compound into the chamber to form a metal oxide, the metal oxide being formed by reacting an oxygen of the oxygen-containing compound with the metal, and to separate the first and second ligands from the metal.
