Abstract: In one embodiment, the semiconductor device includes a stack of alternating interlayer insulating layers and conductive layers on a substrate. Each of the conductive layers extends in a first direction less than a previous one of the conductive layers to define a landing portion of the previous one of the conductive layers. An insulating plug is in one of the conductive layers under one of the landing portions, and a contact plug extends from an upper surface of the one of the landing portions.

Abstract: A vertical non-volatile memory device includes a substrate including a cell region; a lower insulating layer on the substrate; a lower wiring pattern in the cell region having a predetermined pattern and connected to the substrate through the lower insulating layer; and a plurality of vertical channel layers extending in a vertical direction with respect to a top surface of the substrate in the cell region, spaced apart from one another in a horizontal direction with respect to the top surface of the substrate, and electrically connected to the lower wiring pattern. The memory device also includes a plurality of gate electrodes stacked alternately with interlayer insulating layers in the cell region in the vertical direction along a side wall of a vertical channel layer and formed to extend in a first direction along the horizontal direction.
