    Abstract: A vertical semiconductor device may include a first gate pattern, second gate patterns, a first channel hole, a first semiconductor pattern, a second channel hole, and a second semiconductor pattern. The first gate pattern may extend in a first direction on a substrate including first and second regions. The first direction may be parallel to an upper surface of the substrate, and a portion of the first gate pattern on the second region may include a first opening. The second gate patterns may be vertically stacked and spaced apart from each other on the first gate pattern, and each of the second gate patterns may extend in the first direction. The first channel hole may extend through the second gate patterns and the first gate pattern and expose a first portion of the substrate on the first region of the substrate. The first semiconductor pattern may be at a lower portion of the first channel hole. The second channel hole may extend through the second gate patterns and expose a second portion of the substrate on the second region of the substrate, and the second channel hole may be disposed within an area of the first opening in a plan view, wherein the first opening has a larger area than the second channel hole in a plan view. The second semiconductor pattern may be at a lower portion of the second channel hole.

    Abstract: A non-volatile memory device may include a semiconductor substrate and an isolation layer on the semiconductor substrate wherein the isolation layer defines an active region of the semiconductor substrate. A tunnel insulation layer may be provided on the active region of the semiconductor substrate, and a charge storage pattern may be provided on the tunnel insulation layer. An interface layer pattern may be provided on the charge storage pattern, and a blocking insulation pattern may be provided on the interface layer pattern. Moreover, the block insulation pattern may include a high-k dielectric material, and the interface layer pattern and the blocking insulation pattern may include different materials. A control gate electrode may be provided on the blocking insulating layer so that the blocking insulation pattern is between the interface layer pattern and the control gate electrode. Related methods are also discussed.
