    摘要: In non-volatile memory devices and methods of manufacturing the non-volatile memory devices, a barrier layer having an upper portion of silicon nitride and a lower portion of silicon oxide is formed on a substrate by providing a silicon oxide layer on the substrate and performing a radical nitridation process on an upper portion of the silicon oxide layer. A trapping layer including silicon nitride is formed on the barrier layer. A blocking layer and a gate electrode layer are subsequently formed on the trapping layer. The gate electrode layer, the blocking layer, the trapping layer and the barrier layer are then partially etched to provide a gate structure.
