Classification: CPC H | IPC H

Claim 1:
2. 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 the vertical structure comprises a channel layer extending in the vertical direction and a side wall multi-insulating layer on the channel layer,
in the main cell area, there is arranged a first horizontal layer under the support layer, extending in parallel to the upper surface of the first substrate, passing through the side wall multi-insulating layer, and in contact with the channel layer, and
in the edge cell area, there is arranged at least one material layer under the support layer and extending in parallel to the upper surface of the first substrate, and the at least one material layer comprises any one of the first horizontal layer passing through the side wall multi-insulating layer and contacting the channel layer, a first insulating layer in contact with the side wall multi-insulating layer, and a second insulating layer in contact with the side wall multi-insulating layer.
