In one embodiment, a method for forming a dielectric stack on a substrate is provided which includes depositing a first layer of a dielectric material on a substrate surface, exposing the first layer to a nitridation process, depositing a second layer of the dielectric material on the first layer, exposing the second layer to the nitridation process, and exposing the substrate to an anneal process. In another embodiment, a method for forming a dielectric material on a substrate is provided which includes depositing a metal oxide layer substantially free of silicon on a substrate surface, exposing the metal oxide layer to a nitridation process, and exposing the substrate to an anneal process. |
