    Abstract: A stack structure including a plurality of gate electrodes is vertically stacked on a substrate and extends in a first direction. A channel structure includes vertical channels penetrating the stack structure and a horizontal channel connecting the vertical channels. The horizontal channel are provided under the stack structure. First lower wiring patterns are disposed between the substrate and the stack structure and electrically connected to the channel structure. Each first lower wiring pattern includes a first portion and a second portion having different widths from each other in the first direction.

    Abstract: A vertical semiconductor device may include a stacked structure and a plurality of channel structures. The stacked structure may include insulation layers and gate patterns alternately and repeatedly stacked on a substrate. The stacked structure may extend in a first direction parallel to an upper surface of the substrate. The gate patterns may include at least ones of first gate patterns. The stacked structure may include a sacrificial pattern between the first gate patterns. The channel structures may pass through the stacked structure. Each of the channel structures may extend to the upper surface of the substrate, and each of the channel structures may include a charge storage structure and a channel. Ones of the channel structures may pass through the sacrificial pattern in the stacked structure to the upper surface of the substrate, and may extend to the upper surface of the substrate.
