    摘要: In a method of manufacturing a non-volatile memory device, a conductive structure is formed on a substrate. The conductive structure includes a tunnel oxide pattern, a first conductive pattern, a pad oxide pattern and a hard mask pattern. A trench is formed on the substrate using the conductive structure as an etching mask. An inner oxide layer is formed on an inner wall of the trench and sidewalls of the tunnel oxide pattern and the first conductive pattern. The inner oxide layer is cured, thereby forming a silicon nitride layer on the inner oxide layer. A device isolation pattern is formed in the trench, and the hard mask pattern and the pad oxide pattern are removed from the substrate. A dielectric layer and a second conductive pattern are formed on the substrate. Accordingly, the silicon nitride layer prevents-hydrogen (H) atoms from leaking into the device isolation pattern.

    摘要: A non-volatile memory device includes a substrate, resistance patterns, a gate dielectric layer, a gate electrode pattern, a first impurity region and a second impurity region. The substrate has recesses. The recesses are filled with the resistance patterns. The resistance patterns include a material having a resistance that is variable in accordance with a voltage applied thereto. The gate dielectric layer is formed on the substrate. The gate electrode pattern is formed on the gate dielectric layer. The first and second impurity regions are formed in the substrate. The first impurity region and the second impurity region contact side surfaces of the resistance patterns. Further, the resistance patterns, the first impurity region and the second impurity region define a channel region. Thus, the non-volatile memory device may store data using a variable resistance of the resistance patterns so that the non-volatile memory device may have excellent operational characteristics.
