Abstract: A method of forming a nonvolatile memory device includes forming first, second, and third gate structures, with the second and third gate structures including first and second spacer structures formed on a sidewall of the second gate structure and sidewalls of the third gate structure. Impurity regions are formed through ion implantation and the first spacer structure shields the second and third gate structures during ion implantation. The second spacer structure defines resulting impurity regions.

Abstract: A non-volatile memory device comprises a substrate, a control gate electrode on the substrate, and a charge storage region between the control gate electrode and the substrate. A control gate mask pattern is on the control gate electrode, the control gate electrode comprising a control base gate and a control metal gate on the control base gate. A width of the control metal gate is less than a width of the control gate mask pattern. An oxidation-resistant spacer is at sidewalls of the control metal gate positioned between the control gate mask pattern and the control base gate.
