A semiconductor device includes a pattern structure; a stack structure including gate and interlayer insulating layers on the pattern structure; and vertical structures penetrating through the stack structure, contacting the pattern structure. The pattern structure includes a lower pattern layer, an intermediate pattern layer, and an upper pattern layer sequentially stacked, the vertical structures including a vertical memory structure penetrating through the upper pattern and intermediate pattern layers and extending into the lower pattern layer, the intermediate pattern layer including a first portion, a second portion extending from the first portion and having a decreased thickness, and a third portion extending from the first portion, having an increased thickness, and contacting the vertical memory structure. The second portion of the intermediate pattern layer has a side surface that is lowered while forming a surface curved from an upper surface of the first portion and that contacts the upper pattern layer.
