Patent ID: 8613975

Claim:
A method to form a cerium-doped high-κ dielectric film by a chemical phase deposition process, the method comprising delivering at least one metal-source precursor and at least one cerium precursor to a substrate, wherein the at least one cerium precursor corresponds in structure to Formula I: Ce(L) x (Formula I) wherein: L is a β-diketonate; or L is a moiety selected from the group consisting of hexafluoroisopropoxide, 2-dimethylaminoethanolate, 2-methoxyethanolate and 1-methoxy-2-methyl-2-propanolate; and x is 4; wherein the high-κ dielectric film comprises hafnium oxide; zirconium oxide; titanium oxide; or a mixture of hafnium oxide, zirconium oxide and/or titanium oxide.
