    Abstract: Methods of manufacturing vertical semiconductor devices may include forming a mold structure including sacrificial layers and insulating interlayers with a first opening formed therethrough. The sacrificial layers and the insulating interlayers may be stacked repeatedly and alternately on a substrate. The first opening may expose the substrate. Blocking layers may be formed by oxidizing portions of the sacrificial layers exposed by the first opening. A first semiconductor layer pattern, a charge trapping layer pattern and a tunnel insulation layer pattern, respectively, may be formed on the sidewall of the first opening. A second semiconductor layer may be formed on the first polysilicon layer pattern and the bottom of the first opening. The sacrificial layers and the insulating interlayers may be partially removed to form a second opening. The sacrificial layers may be removed to form grooves between the insulating interlayers. Control gate electrodes may be formed in the grooves.

    Abstract: A non-volatile memory device and a non-volatile memory system comprising the same are provided. The non-volatile memory device includes a first stack in which a first conductive pattern and a first dielectric layer are alternately stacked in a first direction on a substrate, a second stack in which a second conductive pattern and a second dielectric layer are alternately stacked in the first direction on the first stack opposite the substrate, a first monitoring channel structure that penetrates the first stack in the first direction, and a second monitoring channel structure that penetrates the second stack in the first direction and is =on the first monitoring channel structure. A width of a top of the first monitoring channel structure opposite the substrate is smaller than a width of a bottom of the second monitoring channel structure adjacent the top of the first monitoring channel structure.

    Abstract: Three-dimensional semiconductor devices are provided. The three-dimensional semiconductor device includes a substrate, a buffer layer on the substrate. The buffer layer includes a material having an etching selectivity relative to that of the substrate. A multi-layer stack including alternating insulation patterns and conductive patterns is provided on the buffer layer opposite the substrate. One or more active patterns respectively extend through the alternating insulation patterns and conductive patterns of the multi-layer stack and into the buffer layer. Related fabrication methods are also discussed.
