Abstract
A semiconductor device including a cell array structure on a semiconductor substrate, the cell array structure including an electrode structure including electrodes and insulating layers vertically and alternately stacked on the semiconductor substrate, and a vertical structure and a penetration contact plug penetrating the electrode structure may be provided. The vertical structure may include a first inner layer, a first outer layer, and a first intermediate layer, and the penetration contact plug may include a second inner layer, a second outer layer, and a second intermediate layer. The electrodes may include a doped semiconductor material, and the first and second outer layers may include the same material. The first and second intermediate layers may include the same material, and the first and second inner layers may include materials different from each other.
