A thermal oxidation process is performed using the trench mask pattern as a diffusion mask to form a thermal oxide layer defining a convex upper surface of the active regions. The thermal oxide layer and the semiconductor substrate are etched using the trench mask pattern as an etch mask to form trenches defining convex upper surfaces of the active regions. The trench mask pattern is removed to expose the convex upper surfaces of the active regions. Gate patterns are formed extending over the active regions.

Abstract: A non-volatile memory device and fabrication methods thereof are provided. A first inter-gate insulating layer is formed to intervene between control gate electrodes and floating gate electrodes in a cell array area. A second inter-gate insulating layer is formed to intervene between a gate electrode and a dummy gate electrode in a peripheral circuit area. The second inter-gate insulating layer has a thickness greater than a thickness of the first inter-gate insulating layer on a top surface of the floating gate electrodes. By reducing the difference between the thickness of the first inter-gate insulating layer on sidewalls of floating gate patterns and the thickness of the second inter-gate insulating layer on a gate electrode pattern, in accordance with the invention, any etching damage to the substrate in the peripheral circuit area can be considerably reduced or prevented during the fabrication process.
