A preliminary charge storage pattern is formed on the tunnel oxide layer and the device isolation pattern by selective deposition of conductive materials. The preliminary charge storage pattern may be removed from the device isolation pattern. The preliminary charge storage pattern remains only on the tunnel oxide layer to form the charge storage pattern on the substrate.
