    Abstract: A method of forming a gate dielectric layer includes forming a first dielectric layer over a semiconductor substrate using a first plasma, performing a first in-situ plasma nitridation of the first dielectric layer to form a first nitrided dielectric layer, forming a second dielectric layer over the first dielectric layer using a second plasma, performing a second in-situ plasma nitridation of the second dielectric layer to form a second nitrided dielectric layer; and annealing the first nitrided dielectric layer and the second nitrided dielectric layer, wherein the gate dielectric layer comprises the first nitrided dielectric layer and the second nitrided dielectric layer. In other embodiments, the steps of forming a dielectric layer using a plasma and performing an in-situ plasma nitridation are repeated so that more than two nitrided dielectric layers are formed and used as the gate dielectric layer.

    Abstract: An insulating layer formed by deposition is annealed in the presence of radical oxygen to reduce bond defects. A substrate is provided. An oxide layer is deposited overlying the substrate. The oxide layer has a plurality of bond defects. The oxide layer is annealed in the presence of radical oxygen to modify a substantial portion of the plurality of bond defects by using oxygen atoms. The anneal, in one form, is an in-situ steam generation (ISSG) anneal. In one form, the insulating layer overlies a layer of charge storage material, such as nanoclusters, that form a gate structure of a semiconductor storage device. The ISSG anneal repairs bond defects by oxidizing defective silicon bonds in the oxide layer when the oxide layer is silicon dioxide.
