    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 semiconductor device includes gate structures including a tunnel insulating layer pattern, a floating gate, a dielectric layer pattern and a control gate sequentially disposed on a substrate. The control gate includes an impurity doped polysilicon layer pattern and a metal layer pattern. The gate structures are spaced apart from each other on the substrate. A capping layer pattern is disposed on a sidewall portion of the metal layer pattern and includes a metal oxide. An insulating layer covers the gate structures and the capping layer pattern. The insulating layer is formed on the substrate and includes an air-gap therein.

    摘要: A vertical type semiconductor device can include a vertical pillar structure that includes a channel pattern with an outer wall. Horizontal insulating structures can be vertically spaced apart from one another along the vertical pillar structure to define first vertical gaps therebetween at first locations away from the outer wall and to define second vertical gaps therebetween at the outer wall, where the second vertical gaps are wider than the first vertical gaps. Horizontal wordline structures can be conformally located in the first and second vertical gaps between the vertically spaced apart horizontal insulating structures, so that the horizontal wordline structures can be vertically thinner across the first vertical gaps than across the second vertical gaps.

    摘要: Manufacturing of a charge trap type memory device can include forming a tunnel insulating layer on a substrate. A charge-trapping layer can be formed on the tunnel insulating layer. A blocking layer can be formed on the charge-trapping layer. Gate electrodes can be formed on the blocking layer and divided by a trench. A portion of the charge-trapping layer aligned with the trench may be converted into a charge-blocking pattern with a vertical side profile by an anisotropic oxidation process.
