摘要: A three-dimensional semiconductor memory device including a peripheral circuit structure on a first substrate, the peripheral circuit structure including peripheral circuits, a second substrate on the peripheral circuit structure, an electrode structure on the second substrate, the electrode structure including a plurality of electrodes that are stacked on the second substrate and a penetrating interconnection structure penetrating the electrode structure and the second substrate may be provided. The penetrating interconnection structure may include a lower insulating pattern, a mold pattern structure on the lower insulating pattern, a protection pattern between the lower insulating pattern and the mold pattern structure, and a penetration plug. The penetration plug may penetrate the mold pattern structure and the lower insulating pattern and may be connected to the peripheral circuit structure. The protection pattern may be at a level lower than that of the lowermost one of the electrodes.

摘要: An integrated circuit device includes a vertical stack of nonvolatile memory cells on a substrate, which are configured as a vertical NAND string of memory cells. This vertical stack of nonvolatile memory cells includes a plurality of gate patterns, which are spaced apart from each other by corresponding electrically insulating layers. A dummy mold structure is also provided on the substrate. The dummy mold structure includes a vertical stack of sacrificial layers, which are spaced apart from each other by corresponding electrically insulating layers. An insulation pattern is provided, which fills a dish-shaped recess in a first one of the sacrificial layers in the vertical stack of sacrificial layers. This insulation pattern has an upper surface that is coplanar with an upper surface of the first one of the sacrificial layers.

摘要: Semiconductor devices and methods of forming the same are provided. The methods may include forming a stacked structure that may include a stacking area and a stepped area and may include first layers and second layers alternately stacked. The second layers may have a stepped shape in the stepped area, and the stepped area may include at least one flat area and at least one inclined stepped area. The methods may also include forming a capping insulating layer covering the stacked structure. The capping insulating layer may include a first capping region having a first upper surface and a second capping region having a second upper surface at a lower level than the first upper surface. The methods may further include patterning the capping insulating layer to form protrusions at least one of which overlaps the stepped area and then planarizing the capping insulating layer.
