A nonvolatile memory device comprises a gate insulating layer formed on a semiconductor substrate, gate patterns formed on the gate insulating layer, insulating layer spacers defining seams and being coupled together in spaces between the gate patterns, the insulating layer spacers being formed on sidewalls of the gate patterns, a height of the insulating layer spacers being lower than a height of the gate patterns, and an auxiliary layer filling the seams.
