    摘要: An electronic device can include a nonvolatile memory cell having DSEs within a dielectric layer. In one aspect, a process of forming the electronic device can include implanting and nucleating a first charge-storage material to form DSEs. The process can also include implanting a second charge-storage material and growing the DSEs such that the DSEs include the first and second charge-storage material. In another aspect, a process of forming the electronic device can include forming a semiconductor layer over a dielectric layer, implanting a charge-storage material, and annealing the dielectric layer. After annealing, substantially none of the charge-storage material remains within a denuded zone within the dielectric layer. In a third aspect, within a dielectric layer, a first set of DSEs can be spaced apart from a second set of DSEs, wherein substantially no DSEs lie between the first set of DSEs and the second set of DSEs.

    摘要: A method forms a split gate memory device. A layer of select gate material over a substrate is patterned to form a first sidewall. A sacrificial spacer is formed adjacent to the first sidewall. Nanoclusters are formed over the substrate including on the sacrificial spacer. The sacrificial spacer is removed after the forming the layer of nanoclusters, wherein nanoclusters formed on the sacrificial spacer are removed and other nanoclusters remain. A layer of control gate material is formed over the substrate after the sacrificial spacer is removed. A control gate of a split gate memory device is formed from the layer of control gate material, wherein the control gate is located over remaining nanoclusters.
