    Abstract: A semiconductor device may include a plurality of gate electrodes apart from each other in a vertical direction on a substrate; a plurality of channel structures penetrating the plurality of gate electrodes and extending in the vertical direction; and a plurality of bit lines arranged on and connected to the plurality of channel structures. The plurality of bit lines may include a plurality of lower bit lines and a plurality of upper bit lines at different vertical levels from each other to constitute at least two layers. The plurality of upper bit lines may be apart from each other in a first horizontal direction and extend in parallel with each other in a second horizontal direction perpendicular to the first horizontal direction. A lower expansion space may be defined between two lower bit lines adjacent to each other among the plurality of lower bit lines.

    Abstract: A three-dimensional semiconductor memory device may include a substrate, a stack structure including interlayer dielectric layers and gate electrodes alternately and repeatedly stacked on the substrate, and vertical channel structures provided in vertical channel holes penetrating the stack structure. Each of the vertical channel structures may include a data storage pattern covering an inner side surface of each of the vertical channel holes, a vertical semiconductor pattern covering the data storage pattern, and a gapfill insulating pattern filling an internal space enclosed by the vertical semiconductor pattern. The vertical semiconductor pattern may have a first surface which is in contact with the gapfill insulating pattern, and a second surface which is in contact with the data storage pattern. A germanium concentration in the vertical semiconductor pattern may decrease in a direction from the first surface toward the second surface.
