Claim 6:
7. The three-dimensional nonvolatile memory device of claim 1, further comprising a support layer arranged under the stacking structure on the first substrate and extending in parallel to the upper surface of the first substrate,
wherein at least one material layer under the support layer and extending in parallel to the upper surface of the first substrate is arranged in the edge cell area,
the through-via wiring area is adjacent to the extension area, and
in the extension area, the main separation insulating layer is lower than the upper surface of the first substrate, and the at least one material layer comprises a first horizontal layer in contact with a side wall multi-insulating layer and thin-film insulating layers on upper and lower surfaces of a second horizontal layer.
