Abstract:
Embodiments of through array contact structures of a 3D memory device and fabricating method thereof are disclosed. The 3D NAND memory device includes an alternating layer stack disposed on a substrate. The alternating layer stack includes a first region including an alternating dielectric stack, and a second region including an alternating conductor/dielectric stack. The memory device further comprises a barrier structure extending vertically through the alternating layer stack to laterally separate the first region from the second region, and multiple through array contacts in the first region each extending vertically through the alternating dielectric stack. At least one through array contact is electrically connected with a peripheral circuit.

Claim (Index 11):
A method for forming a three-dimensional (3D) NAND memory device, comprising:\n forming, on a substrate, an alternating dielectric stack comprising a plurality of dielectric layer pairs, each of the plurality of dielectric layer pairs comprising a first dielectric layer and a second dielectric layer different from the first dielectric layer; forming at least one barrier structure each extending vertically through the alternating dielectric stack, wherein the at least one barrier structure separates the alternating dielectric stack into at least one first region enclosed laterally by at least the barrier structure, and a second region; forming a plurality of slits, and replacing, through the slits, first dielectric layers in the second portion of the alternating dielectric stack with conductor layers to form an alternating conductor/dielectric stack comprising a plurality of conductor/dielectric layer pairs; depositing a conductive material into the slits to form a plurality of slit structures; and forming a plurality of through array contacts in the first region, each through array contact extending vertically through the alternating dielectric stack, to electrically connect at least one of the plurality of through array contacts to at least one peripheral circuit.
