Abstract
A three-dimensional 3D nonvolatile memory device includes vertical channel layers protruding from a substrate; interlayer insulating layers and conductive layer patterns alternately deposited along the vertical channel layers; a barrier metal pattern surrounding each of the conductive layer patterns; a charge blocking layer interposed between the vertical channel layers and the barrier metal patterns; and a diffusion barrier layer interposed between the barrier metal patterns and the charge blocking layer.
