Patent ID: 7572731

Claim:
A method of forming a metal-containing layer on a substrate, the method comprising: providing a substrate; providing a vapor comprising at least one compound of the formula (Formula I): wherein: M is selected from the group consisting of a Group 2 metal, yttrium, a Lanthanide, and combinations thereof; each L is independently an anionic ligand; each Y is independently a neutral ligand; n represents the valence state of the metal; z is from 0 to 10; x is from 1 to n; and each R 1 , R 2 , R 3 , R 4 , and R 5 is independently hydrogen or an organic group; with the proviso that one or more of the following apply: R 1 is different than R 5 , or R 2 is different than R 4 ; and contacting the vapor comprising the at least one compound of Formula I with the substrate to form a metal-containing layer on at least one surface of the substrate using a vapor deposition process.
