Abstract
A semiconductor device includes a semiconductor structure that includes a substrate having a first region and a second region, gate electrodes stacked and spaced apart from each other in a first direction, extend at different lengths in a second direction on the second region, and include pad regions, interlayer insulating layers alternately stacked with the gate electrodes, channel structures penetrating the gate electrodes, extending in the first direction, and each including a channel layer, contact plugs penetrating the pad regions and extending in the first direction on the second region, and contact insulating layers between the gate electrodes and between ones of the contact plugs below the pad regions. The pad regions and the contact insulating layers protrude from the interlayer insulating layers toward the contact plugs in a horizontal direction.
