Patent ID: 8530322

Claim:
A method of fabricating a semiconductor assembly, the method comprising: depositing a first metal oxide layer above an electrode, wherein the electrode comprises a metal nitride material, and wherein the first metal oxide layer comprises zirconium oxide, wherein the first metal oxide layer is deposited using a first oxygen reagent and a first metal precursor at a temperature of less than or equal to 220° C.; and depositing a second metal oxide layer above the first metal oxide layer, wherein the second metal oxide layer comprises zirconium oxide, wherein the second metal oxide layer is deposited using a second oxygen reagent and a second metal precursor at a temperature between about 250° C. and about 300° C., wherein the first metal precursor comprises a low temperature Zr alkylamido-based precursor, wherein the second metal precursor comprises a high temperature Zr alkylamido cyclopentadienyl, and wherein the second oxygen reagent is different from the first oxygen reagent.
