    Abstract: A semiconductor device can include a first substrate and conductive patterns on the first substrate, where the conductive patterns are disposed in stacks vertically extending from the substrate. An active pillar can be on the first substrate vertically extend from the first substrate throughthe conductive patterns to provide vertical string transistors on the first substrate. A second substrate can be on the conductive patterns and the active pillar opposite the first substrate. A peripheral circuit transistor can be on the second substrate opposite the first substrate, where the peripheral circuit transistor can be adjacent to and overlap an uppermost pattern of the conductive patterns.

    Abstract: A semiconductor memory device includes a first semiconductor chip and a second semiconductor chip. Each semiconductor chip of the first and second semiconductor chips may include a cell array region and a peripheral circuit region. The cell array region may include an electrode structure including electrodes sequentially stacked on a body conductive layer and vertical structures extending through the electrode structure and connected to the body conductive layer. The peripheral circuit region may include a residual substrate on the body conductive layer and on which a peripheral transistor is located. A bottom surface of the body conductive layer of the second semiconductor chip may face a bottom surface of the body conductive layer of the first semiconductor chip.

    Abstract: A three-dimensional semiconductor device is disclosed. The device may include an electrode structure that can include a plurality of electrodes that are stacked on a substrate and extend in a first direction. Vertical structures can penetrate the electrode structure to provide a plurality of columns spaced apart from each other in a second direction crossing the first direction. The plurality of columns can include first and second edge columns located adjacent to respective opposite edges of the electrode structure, and the plurality of columns can include a center column located between the first and second edge columns. Distances between adjacent ones of the plurality of columns can decrease in a direction from the first and second edge columns toward the center column.

    Abstract: A method of manufacturing a vertical type memory device includes stacking a first lower insulating layer, one layer of a lower sacrificial layer and a second lower insulating layer on a substrate, forming a stacking structure by stacking sacrificial layers and insulating layers, and etching an edge portion of the stacking structure to form a preliminary stepped shape pattern structure. The preliminary stepped shape pattern structure has a stepped shape edge portion. A pillar structure making contact with a surface of the substrate is formed. The preliminary stepped shape pattern structure, the lower sacrificial layer, and the first and second lower insulating layers are partially etched to form a first opening portion and a second opening portion to form a stepped shape pattern structure. The second opening portion cuts at least an edge portion of the lower sacrificial layer.
