    摘要: A method of manufacturing a nonvolatile memory device includes forming a tunnel dielectric layer, a charge storage layer, and a hard mask layer on a substrate in sequential order. Active portions are defined by forming trenches in the substrate. A tunnel dielectric pattern, a preliminary charge storage pattern, and a hard mask pattern are formed on each of the active portions in sequential order by sequentially patterning the hard mask layer, the charge storage layer, the tunnel dielectric layer, and the substrate. A capping pattern is formed covering an upper surface of the trenches such that a first void remains in a lower portion of the trenches, the capping pattern including etch particles formed by etching the hard mask pattern through a sputtering etch process.

    摘要: A semiconductor memory device includes a stack including gate electrodes sequentially stacked on a substrate, a vertical insulating structure penetrating the stack vertically with respect to the gate electrodes, a vertical channel portion disposed on an inner side surface of the vertical insulating structure, and a common source region formed in the substrate and spaced apart from the vertical channel portion. A bottom region of the vertical channel portion has a protruding surface in contact with a bottom region of the vertical insulating structure.
