    摘要: Fabrication of a nonvolatile memory device includes sequentially forming a tunnel oxide layer, a first conductive layer, and a nitride layer on a semiconductor substrate. A stacked pattern is formed from the tunnel oxide layer, the first conductive layer, and the nitride layer and a trench is formed in the semiconductor substrate adjacent to the stacked pattern. An oxidation process is performed to form a sidewall oxide layer on a sidewall of the trench and the first conductive layer. Chlorine is introduced into at least a portion of the stacked pattern subjected to the oxidation process. Introducing Cl into the stacked pattern may at least partially cure defects that are caused therein during fabrication of the structure.
