    摘要: Example embodiments may provide a nonvolatile memory device. The example embodiment nonvolatile memory device may include a floating gate structure formed on a semiconductor substrate with a gate insulating layer between them and/or a control gate formed adjacent to the floating gate with a tunneling insulation layer between them. The floating gate may include a first floating gate formed on the gate insulating layer, a second floating gate formed on the first floating gate with a first insulating pattern between them, and/or a gate connecting layer formed on at least one sidewall of the first insulating pattern so that the gate conducting layer may electrically connect the first floating gate and the second floating gate. The second floating gate may have a tip formed at its longitudinal end that may not contact the gate connecting layer.

    摘要: In a method of manufacturing a semiconductor device, a tunnel insulation layer is formed on a substrate. A charge trapping layer is formed on the tunnel insulation layer. A protection layer pattern or a mold is formed on the charge trapping layer. Charge trapping layer patterns are formed on the tunnel insulation layer by etching the charge trapping layer using the protection layer pattern or the mold. The charge trapping layer patterns may be spaced apart from each other. Blocking layers are formed on the charge trapping layer patterns, respectively. A gate electrode is formed on the blocking layers and the tunnel insulation layer using the protection layer pattern or the mold.
