摘要: A semiconductor device includes gate structures including a tunnel insulating layer pattern, a floating gate, a dielectric layer pattern and a control gate sequentially disposed on a substrate. The control gate includes an impurity doped polysilicon layer pattern and a metal layer pattern. The gate structures are spaced apart from each other on the substrate. A capping layer pattern is disposed on a sidewall portion of the metal layer pattern and includes a metal oxide. An insulating layer covers the gate structures and the capping layer pattern. The insulating layer is formed on the substrate and includes an air-gap therein.

摘要: An insulating pattern is disposed on a surface of a semiconductor substrate and includes a silicon oxynitride film. A conductive pattern is disposed on the insulating pattern. A data storage pattern and a vertical channel pattern are disposed within a channel hole formed to vertically penetrate the insulating pattern and the conductive pattern. The data storage pattern and the vertical channel pattern are conformally stacked along sidewalls of the insulating pattern and the conductive pattern. A concave portion is formed in the semiconductor substrate adjacent to the insulating pattern. The concave portion is recessed relative to a bottom surface of the insulating pattern.
