    Abstract: A semiconductor device may include a first substrate structure including a substrate, circuit elements on the substrate, and first bonding layers on the circuit elements, and a second substrate structure on the first substrate structure. The second substrate structure may include a plate layer, an intermediate insulating layer below the plate layer and including silicon nitride, gate electrodes below the intermediate insulating layer and stacked to be spaced apart from each other in a vertical direction, a channel structure in a channel hole passing through the intermediate insulating layer and the gate electrodes and including a semiconductor layer, and second bonding layers connected to the first bonding layers. The channel hole may have a first width in a first portion passing through the gate electrodes and a second width, wider than the first width, in a second portion passing through the intermediate insulating layer.

    Abstract: A three-dimensional non-volatile memory device includes a memory cell array including a plurality of memory cells repeatedly arranged in a first lateral direction, a second lateral direction, and a vertical direction on a substrate. The first lateral direction and the second lateral direction are parallel to a main surface of the substrate and perpendicular to each other, and the vertical direction is perpendicular to the main surface of the substrate. The memory cell array includes a plurality of horizontal channel regions and a vertical word line. The plurality of horizontal channel regions extend in the first lateral direction on the substrate. The plurality of horizontal channel regions overlap each other and are apart from each other in the vertical direction. The vertical word line passes through the plurality of horizontal channel regions in the vertical direction.
