    Abstract: Disclosed is a three-dimensional semiconductor memory device comprising a peripheral circuit structure on a first substrate, a second substrate on the peripheral circuit structure, first to fourth stack structures spaced apart in a first direction on the second substrate, first and second support connectors between the second and third stack structures, third and fourth support connectors between the third and fourth stack structures, and a through dielectric pattern penetrating the first stack structure and the second substrate. A first distance between the first and second support connectors is different from a second distance between the third and fourth support connectors.

    Abstract: A semiconductor device includes an active pattern extending on a substrate in a first direction, divided into a plurality of regions by a separation region, and having a first edge portion exposed toward the separation region; first, second and third channel layers vertically separated and sequentially disposed on the active pattern; a first gate electrode extending in a second direction, intersecting the active pattern, and surrounding the first, second and third channel layers; source/drain regions disposed on the active pattern, on at least one side of the first gate electrode, and contacting the first, second and third channel layers; a semiconductor structure including first semiconductor layers and second semiconductor layers alternately stacked on the active pattern, and having a second edge portion exposed toward the separation region; and a blocking layer covering at least one of an upper surface, side surfaces, or the second edge portion, of the semiconductor structure.
