    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.

    Abstract: A semiconductor device includes a substrate; a stack structure on the substrate and including an alternating stack of interlayer insulating layers and gate electrodes; first and second separation regions each extending through the stack structure and extending in a first direction; a first upper separation region between the first and second separation regions and extending through a portion of the stack structure; a plurality of channel structures between the first and second separation regions and extending through the stack structure; and a plurality of first vertical structures each extending through a particular one of the first and second separation regions. Each of the first and second separation regions has a first width in a second direction that is perpendicular to the first direction. Each first vertical structure has a second width in the second direction, the second width being greater than the first width.
