Abstract:
A semiconductor device includes a substrate, a cell stack structure, a channel layer, a peripheral contact plug, and first dummy conductive rings. The substrate may include a first region and a second region. The cell stack structure may include interlayer insulating layers and conductive patterns, which are alternately stacked over the first region of the substrate. The channel layer may penetrate the cell stack structure. The peripheral contact plug may extend in parallel to the channel layer over the second region of the substrate. The first dummy conductive rings may be disposed at the same levels as the conductive patterns, are spaced apart from the peripheral contact plug, and surround the peripheral contact plug.

Claim (Index 8):
A semiconductor device comprising:\n a substrate including a first region and a second region; a cell stack structure including interlayer insulating layers and conductive patterns, which are alternately stacked over the first region of the substrate; a channel layer penetrating the cell stack structure; a dummy buffer stack structure including dummy interlayer insulating layers and sacrificial insulating layers, which are alternately stacked over the second region of the substrate; a peripheral contact hole penetrating the dummy buffer stack structure; a peripheral contact plug disposed in the peripheral contact hole; and first dummy conductive rings disposed between protruding portions of the dummy interlayer insulating layers, which protrude farther toward the peripheral contact hole than the sacrificial insulating layers.
