Patent ID: 8399874

Claim:
A vertical nonvolatile memory device comprising: a substrate; a conductor-insulator horizontal structure disposed on the substrate, the conductor-insulator horizontal structure comprising horizontal conductive layers extending in one direction and horizontal insulating layers extending in the same direction as that in which the horizontal conductive layers extend, the horizontal conductive layers and the horizontal insulating layers being alternately stacked on the substrate along the direction which is perpendicular to the substrate; a memory layer disposed at a side of the conductor-insulator horizontal structure and formed of a memory material; a complex conductor-insulator structure disposed at a side of the memory layer such that the memory layer is disposed between the conductor-insulator horizontal structure and the complex conductor-insulator structure, the complex conductor-insulator structure comprising independent conductor-insulator structures and vertical separation films that are alternately arranged on the substrate in the direction in which the horizontal conductive layers extend, each of the independent conductor-insulator structures comprising independent conductive layers and independent insulating layers that are alternately stacked on the substrate along the direction which is perpendicular to the substrate; a selective diode disposed at a side of the complex conductor-insulator structure such that the complex conductor-insulator structure is disposed between the memory layer and the selective diode; and a conductor-insulator vertical structure disposed at a side of the selective diode such that the selective diode is disposed between the complex conductor-insulator structure and the conductor-insulator vertical structure, the conductor-insulator vertical structure comprising vertical conductive films and vertical insulating films that are disposed on the substrate, the vertical conductive films and the vertical insulating films being alternately arranged in the direction in which the horizontal conductive layers extend.
