    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 device includes a gate structure on a channel region of a semiconductor substrate adjacent to a source/drain region therein and a surface insulation layer directly on the source/drain region of the substrate adjacent to the gate structure. The device further includes a spacer on a sidewall of the gate structure adjacent to the source/drain region. A portion of the surface insulation layer adjacent the gate structure is sandwiched between the substrate and the spacer. An interface between the surface insulation layer and the source/drain region includes a plurality of interfacial states. Portions of the source/drain region immediately adjacent the interface define a carrier accumulation layer having a greater carrier concentration than other portions thereof. The carrier accumulation layer extends along the interface under the spacer. Related methods are also discussed.
