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 14):
A semiconductor device comprising:\n a substrate including a first region and a second region; a peripheral circuit disposed over the substrate; a cell stack structure disposed on the peripheral circuit over the first region of the substrate; a dummy buffer stack structure disposed on the peripheral circuit over the second region of the substrate; cell pillars extending along a first direction to penetrate the cell stack structure; dummy pillars extending along the first direction to penetrate the dummy buffer stack structure; a peripheral contact hole penetrating the dummy buffer stack structure between the dummy pillars; an insulating layer filled in the peripheral contact hole; and a peripheral contact plug penetrating the insulating layer, wherein the dummy buffer stack structure includes: sacrificial insulating layers stacked over the second region of the substrate to be spaced apart from each other in the first direction; dummy conductive patterns extending toward the peripheral contact holes from sidewalls of the sacrificial insulating layers, the dummy conductive patterns being penetrated by the dummy pillars; and a dummy interlayer insulating layer disposed between the sacrificial insulating layers adjacent to each other in the first direction, the dummy interlayer insulating layer extending toward the peripheral contact hole to overlap with the dummy conductive patterns.
