Abstract
Disclosed are semiconductor devices and electronic systems including the same. A semiconductor device includes a substrate including a cell array region and a connection region, an electrode structure including electrodes and dielectric layers that are stacked in alternating fashion, each of the plurality of electrodes including an electrode part on the cell array region and a pad part on the connection region, dummy vertical structures on the connection region and penetrating the pad parts of each of the electrodes, and a cell contact plug on the connection region and coupled to the pad part of each of the electrodes. A thickness of the pad part is greater than that of the electrode part. The pad part has a lower portion connected to the electrode part and an upper portion on the lower portion. Between adjacent ones of the dummy vertical structures, a width of the upper portion is not less than that of the lower portion.
