    Abstract: A vertical memory device includes gate electrode structures, channels, first to third division patterns, and a first support layer. The gate electrode structure includes gate electrodes stacked in a first direction, and extends in a second direction. The gate electrode structures are spaced apart from one another in a third direction. The first division pattern extends in the second direction between the gate electrode structures. The second and third division patterns are alternately disposed in the second direction between the gate electrode structures. The first support layer is on the gate electrode structures at substantially the same height as upper portions of the first and second division patterns, and contacts the upper portions of the first and second division patterns. The upper portions of the first and second division patterns are arranged in a zigzag pattern in the second direction in a plan view.

    Abstract: A semiconductor device includes a first structure including a peripheral circuit and a second structure on the first structure. The second structure includes: a stack structure including first and second stack structures; separation structures passing through the first stack structure; a memory vertical structure between the separation structures and passing through the first stack structure; and a capacitor including first and second capacitor electrodes passing through the second stack structure and extending parallel to each other. The first stack structure includes spaced apart gate electrodes and interlayer insulating layers alternately stacked therewith. The second stack structure includes spaced apart first insulating layers, and second insulating layers alternately stacked therewith. Each of the first and second capacitor electrodes has a linear shape. The first and second insulating layers include a different material from each other. The second insulating layers include the same material as the interlayer insulating layers.

    Abstract: A vertical memory device includes a gate electrode structure formed on a substrate including a cell array region and a pad region, a channel, contact plugs, and support structures. The gate electrode structure includes gate electrodes extending in a second direction and stacked in a staircase shape in a first direction on the pad region. The channel extends through the gate electrode structure on the cell array region. The contact plugs contact corresponding ones of steps, respectively, of the gate electrode structure. The support structures extend through the corresponding ones of the steps, respectively, and extend in the first direction on the pad region. The support structure includes a filling pattern and an etch stop pattern covering a sidewall and a bottom surface thereof. An upper surface of each of the support structures is higher than that of the channel.
