    摘要: Three-dimensional (3D) nonvolatile memory devices include a substrate having a well region of second conductivity type (e.g., P-type) therein and a common source region of first conductivity type (e.g., N-type) on the well region. A recess is provided, which extends partially (or completely) through the common source region. A vertical stack of nonvolatile memory cells are provided on the substrate. This vertical stack of nonvolatile memory cells includes a vertical stack of spaced-apart gate electrodes and a vertical active region, which extends on sidewalls of the vertical stack of spaced-apart gate electrodes and on a sidewall of the recess. Gate dielectric layers are provided, which extend between respective ones of the vertical stack of spaced-apart gate electrodes and the vertical active region. The gate dielectric layers may include a composite of a tunnel insulating layer, a charge storage layer, a relatively high bandgap barrier dielectric layer and a blocking insulating layer having a relatively high dielectric strength.

    摘要: Provided are three-dimensional semiconductor devices. The devices may include gap-fill insulating patterns configured to upwardly extend from a substrate and an electrode structure defined by sidewalls of the gap-fill insulating patterns. Vertical structures may be provided between adjacent ones of the gap-fill insulating patterns to penetrate the electrode structure, and the vertical structures may include first and second rows of the vertical structures. A separation pattern may be provided between the first and second rows of vertical structures and include a separation semiconductor layer. The separation pattern extends along a direction parallel to the first and second rows of vertical structures.
