Abstract:
Embodiments of interconnect structures of a three-dimensional (3D) memory device and method for forming the interconnect structures are disclosed. In an example, a 3D NAND memory device includes a semiconductor substrate, an alternating layer stack disposed on the semiconductor substrate, and a dielectric structure, which extends vertically through the alternating layer stack, on an isolation region of the substrate. Further, the alternating layer stack abuts a sidewall surface of the dielectric structure and the dielectric structure is formed of a dielectric material. The 3D memory device additionally includes one or more through array contacts that extend vertically through the dielectric structure and the isolation region, and one or more channel structures that extend vertically through the alternating layer stack.

Claim (Index 16):
A three-dimensional (3D) memory device, comprising:\n a substrate with an isolation structure; an alternating conductor/dielectric layer stack disposed on the substrate; a dielectric structure on the isolation structure and extending vertically through the alternating conductor/dielectric layer stack, wherein the alternating conductor/dielectric layer stack abuts a sidewall surface of the dielectric structure and the dielectric structure is formed of a dielectric material; channel structures extending vertically through the alternating conductor/dielectric layer stack; and through array contacts (TAC) extending vertically through the dielectric and the isolation structures.
