Patent attributes
A non-volatile memory is provided. A substrate has at least two isolation structures therein to define an active area. A well is located in the substrate. A shallow doped region is located in the well. At least two stacked gate structures are located on the substrate. Pocket doped regions are located in the substrate at the peripheries of the stacked gate structures; each of the pocket doped regions extends under the stacked gate structure. Drain regions are located in the pocket doped regions at the peripheries of the stacked gate structures. An auxiliary gate layer is located on the substrate between the stacked gate structures. A gate dielectric layer is located between the auxiliary gate layer and the substrate and between the auxiliary gate layer and the stacked gate structure. Plugs are located on the substrate and extended to connect with the pocket doped region and the drain regions therein.
