    摘要: Nonvolatile memory devices include at least four cylindrical-shaped channel regions, which extend vertically from portions of a substrate located at respective vertices of at least one rhomboid when viewed in a vertical direction relative to a surface of the substrate. A charge storage layer (e.g., ONO layer) is provided on an outer sidewall of each of the cylindrical-shaped channel regions. In addition, to achieve a high degree of integration, a plurality of vertically-stacked gate electrodes are provided, which extend adjacent each of the cylindrical-shaped channel regions.

    摘要: A vertical structure non-volatile memory device in which a gate dielectric layer is prevented from protruding toward a substrate; a resistance of a ground selection line (GSL) electrode is reduced so that the non-volatile memory device is highly integrated and has improved reliability, and a method of manufacturing the same are provided. The method includes: sequentially forming a polysilicon layer and an insulating layer on a silicon substrate; forming a gate dielectric layer and a channel layer through the polysilicon layer and the insulating layer, the gate dielectric layer and the channel layer extending in a direction perpendicular to the silicon substrate; forming an opening for exposing the silicon substrate, through the insulating layer and the polysilicon layer; removing the polysilicon layer exposed through the opening, by using a halogen-containing reaction gas at a predetermined temperature; and filling a metallic layer in the space formed by removing the polysilicon layer.

    摘要: A three-dimensional (3D) nonvolatile memory device includes a vertical stack of nonvolatile memory cells on a substrate having a region of first conductivity type therein. A dopant region of second conductivity type is provided in the substrate. This dopant region forms a P—N rectifying junction with the region of first conductivity type and has a concave upper surface that is recessed relative to an upper surface of the substrate upon which the vertical stack of nonvolatile memory cells extends. An electrically insulating electrode separating pattern is provided, which extends through the vertical stack of nonvolatile memory cells and into the recess in the dopant region of second conductivity type.

    摘要: A semiconductor memory device includes insulating patterns and gate patterns alternately stacked on a substrate, a channel structure that intersects the insulating patterns and the gate patterns and connected to the substrate, a charge storage structure between the channel structure and the gate patterns, and a contact structure on the substrate at a side of the insulating patterns and the gate patterns. One of the gate patterns includes a first barrier pattern between a first insulating pattern of the insulating patterns and a second insulating pattern of the insulating patterns adjacent the first insulating pattern in a first direction perpendicular to a main surface of the substrate, the first barrier pattern defining a concave region between a first portion of the first barrier pattern extending along the first insulating pattern and a second portion extending along the second insulating pattern, and a metal pattern in the concave region.
