Abstract:
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 extends partially (or completely) through the common source region. A vertical stack of nonvolatile memory cells on the substrate 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 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.

Claim (Index 1):
A nonvolatile memory device, comprising:\n a substrate having a well region of second conductivity type therein and a common source region of first conductivity type on the well region; a recess in said substrate, said recess extending at least partially through the common source region; and a vertical stack of nonvolatile memory cells on said substrate, said vertical stack of nonvolatile memory cells comprising:\n a vertical stack of spaced-apart gate electrodes on said substrate; \n a vertical active region on sidewalls of the vertical stack of spaced-apart gate electrodes and on a sidewall of the recess; and \n gate dielectric layers extending between respective ones of the vertical stack of spaced-apart gate electrodes and said vertical active region.
