    Abstract: A semiconductor device includes a plate layer, gate electrodes on the plate layer, interlayer insulating layers that are alternately stacked with the gate electrodes, and channel structure that extends into the gate electrodes, where the channel structure includes a channel filling layer, a channel layer that at least partially surrounds the channel filling layer, charge storage layers between the gate electrodes and the channel layer, a first dielectric layer between the gate electrodes and the charge storage layers, and a second dielectric layer between the channel layer and the charge storage layers, where the channel layer includes first convex portions that extend toward the channel filling layer from a side surface of the channel layer that contacts the channel filling layer, and where vertices of the first convex portions are at first levels in the first direction that are between each level of a pair of adjacent gate electrodes.
