Abstract
A semiconductor device includes a first substrate structure including a first decoder circuit region, a second decoder circuit region, and a page buffer circuit region, and a second substrate structure connected to the first substrate structure. The second substrate structure includes a first cell structure that includes first horizontally extending gate electrodes, and a second cell structure that includes second horizontally extending gate electrodes. The second cell structure is disposed below the first cell structure. A first stair structure is disposed to one side of the first and second cell structures, and a second stair structure is disposed to a second side opposite the first side. a dummy structure is disposed below the first stair structure. First contact plugs pass through the first stair structure and the first dummy structure and are respectively connected to the first gate electrodes, and second contact plugs pass through the second stair structure and are respectively connected to the second gate electrodes.
