    • A method of manufacturing a non-volatie memory device includes forming a tunnel insulating layer on a substrate, forming a conductive pattern on the tunnel insulating layer, forming a lower dielectric layer on the conductive pattern, performing a first heat treatment process to density the lower dielectric layer, and forming a middle dielectric layer having an energy band gap smaller than that of the lower dielectric layer on the first heat-treated lower dielectric layer. The method further includes forming an upper dielectric layer including a material substantially identical to that of the lower dielectric layer on the middle dielectric layer, performing a second heat treatment process to densify the middle dielectric layer and the upper dielectric layer and forming a conductive layer on the second heat-treated upper dielectric layer.
    • 制造非挥发性记忆装置的方法包括在基板上形成隧道绝缘层,在隧道绝缘层上形成导电图案,在导电图案上形成下介电层,进行第一热处理工艺以密度较低 并且形成具有比第一经热处理的下电介质层上的下介电层的能带隙小的能带隙的中间电介质层。 该方法还包括形成上介电层,其包括与中间介电层上的下电介质层的材料基本相同的材料,执行第二热处理工艺以使中介电层和上电介质层致密并形成导电层 第二热处理的上介电层。
