Patent ID: 7576378

Claim:
A vapor deposition system comprising: a vapor deposition chamber; one or more vessels comprising one or more precursor compounds having the formula L n M 1 O x (keto) y (Formula I); and one or more vessels comprising one or more one precursor compounds of the formula M 2 Y Z (Formula II), wherein: M 1 and M 2 are each independently a metal selected from the group of metals consisting of La, Ce, Pr, Gd, Al, Si, and mixtures thereof; each L group is a neutral or anionic supporting ligand; each “keto” is independently a diketonate or ketoimine ligand; each Y group is independently a halogen (X), R 1 , or an amine of the formula NR 2 R 3 ), wherein each R 1 , R 2 , and R 3 is independently hydrogen or an organic group; n is 0 to 5; x is 0 to 3; y is 1 to 5 and is dependent on the oxidation state of M 1 and on the value of n; and z is at least one and is dependent on the oxidation state of M 2 .
