  • Patent number: 9564451
    Abstract: A semiconductor device may include a substrate, conductive patterns stacked to be spaced apart from each other on the substrate, contact plugs coming in contact with the respective conductive patterns, and first and second slit insulating layers of a first group penetrating the conductive patterns. The substrate may include a cell area and a contact area extending along a first direction from the cell area. The conductive patterns may be form a step structure. The first slit insulating layers of the first group may be opposite to each other in a second direction with any one of the contact plugs, interposed therebetween. The second slit insulating layers of the first group, which extend along the first direction in the contact area, may be opposite to each other in the second direction with the first slit insulating layers of the first group and the contact plugs, interposed therebetween.
