Abstract
A semiconductor device includes a substrate including cell and dummy regions, first channel structures on the cell region and extending in a first direction vertical with respect to the substrate, gate lines surrounding outer sidewalls of the first channel structures and extending in a second direction parallel to the substrate, the gate lines being spaced apart from each other along the first direction, cutting lines between the gate lines on the cell region and extending in the second direction, dummy patterns spaced apart from each other along the first direction on the dummy region, the dummy patterns having a stepped shape along a third direction parallel to the top surface of the substrate and perpendicular to the second direction, at least a portion of the dummy patterns including a same conductive material as that in the gate lines, and dummy lines through the dummy patterns.
