Abstract
A semiconductor device may include a gate structure including conductive layers and insulating layers that are alternately stacked and including a stair structure for exposing at least one of the conductive layers, a contact plug that extends through the gate structure and that is electrically connected to a uppermost conductive layer that is exposed by the stair structure, and insulating spacers that are disposed between remaining conductive layers, among the conductive layers, and the contact plug. The insulating layers may each have a first thickness, and the insulating spacers may each have a second thickness smaller than the first thickness.
