    摘要： A semiconductor device includes a first stack group having first interlayer insulating layers and first gate layers, alternately and repeatedly stacked on a substrate and a second stack group comprising second interlayer insulating layers and second gate layers, alternately and repeatedly stacked on the first stack group. Separation structures pass through the first and second stack groups and include a first separation region and a second separation region. A vertical structure passes through the first and second stack groups and includes a first vertical region and a second vertical region. A conductive line is electrically connected to the vertical structure on the second stack group. A distance between an upper end of the first vertical region and an upper surface of the substrate is greater than a distance between an upper end of the first separation region and an upper surface of the substrate.

    摘要： 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.
