    摘要: A vertical memory device may include a substrate, a first selection line on the substrate, a plurality of word lines on the first selection line, a second selection line on the plurality of word lines, and a semiconductor channel. The first selection line may be between the plurality of word lines and the substrate, and the plurality of word lines may be between the first and second selection lines. Moreover, the first and second selection lines and the plurality of word lines may be spaced apart in a direction perpendicular with respect to a surface of the substrate. The semiconductor channel may extend away from the surface of the substrate adjacent sidewalls of the first and second selection lines and the plurality of word lines. In addition, portions of the semiconductor channel adjacent the second selection line may be doped with indium and/or gallium. Related methods are also discussed.

    摘要: A method of manufacturing a vertical memory device includes forming alternating and repeating insulating interlayers and sacrificial layers on a substrate, the sacrificial layers including polysilicon or amorphous silicon, forming channel holes through the insulating interlayers and the sacrificial layers, forming channels in the channel holes, etching portions of the insulating interlayers and the sacrificial layers between adjacent channels to form openings, removing the sacrificial layers to form gaps between the insulating interlayers, and forming gate lines in the gaps.

    摘要: A vertical memory device includes a channel array, a charge storage layer structure, multiple gate electrodes and a dummy pattern array. The channel array includes multiple channels, each of which is formed on a first region of a substrate and is formed to extend in a first direction substantially perpendicular to a top surface of the substrate. The charge storage layer structure includes a tunnel insulation layer pattern, a charge storage layer pattern and a blocking layer pattern, which are sequentially formed on a sidewall of each channel in the second direction substantially parallel to the top surface of the substrate. The gate electrodes arranged on a sidewall of the charge storage layer structure and spaced apart from each other in the first direction. The dummy pattern array includes multiple dummy patterns, each of which is formed on a second region adjacent the first region of the substrate and is formed to extend in the first direction.
