    Abstract: A semiconductor device includes a stack structure of alternating interlayer insulating layers and gate electrodes, a separation structure vertically penetrating the stack structure and extending in a first direction, to separate the gate electrodes in a second direction, and vertical structures vertically penetrating the stack structure and arranged at a constant pitch. The vertical structures are arranged along array lines sequentially arranged in the second direction away from a side of the separation structure in a plan view. The vertical structures include a channel structure including a channel layer, a contact structure including a metal plug having an upper surface on a level higher than that of an upper surface of the channel structure, and a dummy structure disposed adjacent to the contact structure. The channel structure, the dummy structure, and the contact structure are disposed to be aligned with each other on at least one of the array lines.

    Abstract: The present disclosure relates to three-dimensional (3D) semiconductor memory devices and electronic systems. An example 3D semiconductor memory device comprises a substrate that includes a cell array region and a connection region, a structure in which a plurality of dielectric layers and a plurality of gate electrodes are alternately stacked on the substrate, a plurality of dummy vertical structures that extend through the structure on the connection region, and a gate contact that extends through the structure on the connection region and is connected to one gate electrode of the plurality of gate electrodes. The gate contact is between the plurality of dummy vertical structures in a plan view. The gate contact includes a first portion and a plurality of second portions that extend between the plurality of dummy vertical structures.

    Abstract: Disclosed are three-dimensional semiconductor memory devices, methods of manufacturing the same, and electronic systems including the same. The device includes a peripheral circuit structure on a substrate, and a cell array structure including a stack structure that includes gate electrodes on the peripheral circuit structure, a first source conductive pattern on the stack structure, and vertical channel structures in vertical channel holes that penetrate the stack structure and the first source conductive pattern. The vertical channel structure includes a data storage pattern on a sidewall of the vertical channel hole, a vertical semiconductor pattern on the data storage pattern, and a second source conductive pattern on the vertical semiconductor pattern and surrounded by the data storage pattern. A thickness of the data storage pattern between the first source conductive pattern and the second source conductive pattern is greater than it is between the stack structure and the vertical semiconductor pattern.

    Abstract: A three-dimensional semiconductor memory device includes a substrate, and a stack structure on the substrate. The stack structure includes first blocks that extend in a first direction and are arranged in a second direction intersecting the first direction, and a second block that is between the first blocks; separation structures that extend in the first direction and are arranged in the second direction between the first blocks and between the first and second blocks; vertical channel structures that penetrate the first blocks and contact the substrate; and through-via structures that penetrate the second block and the substrate. A width of each of the first blocks in the second direction is equal to a width of the second block in the second direction.
