Patent ID: 7642163

Claim:
A process of forming an electronic device including a nonvolatile memory cell, the process comprising: forming a dielectric layer over a substrate; and forming a set of discontinuous storage elements within the dielectric layer, wherein forming the set of discontinuous storage elements includes: implanting a first charge-storage material into the dielectric layer at a first projected range that is within the dielectric layer; nucleating the first charge-storage material to form the set of discontinuous storage elements, wherein after nucleating the first charge-storage material: the set of discontinuous storage elements lies within the dielectric layer; and the set of discontinuous storage elements includes the first charge-storage material; implanting a second charge-storage material into the dielectric layer at a second projected range that is within the dielectric layer; and growing the set of discontinuous storage elements, wherein after growing the set of discontinuous storage elements, the set of discontinuous storage elements includes the first charge-storage material and the second charge-storage material.
