Abstract:
A first-tier structure including a first alternating stack of first insulating layers and first spacer material layers is formed over a substrate. First-tier memory openings and at least one type of first-tier contact openings can be formed simultaneously employing a same anisotropic etch process. The first-tier contact openings formed over stepped surfaces of the first alternating stack may extend through the first alternating stack, or may stop on the stepped surfaces. Sacrificial first-tier opening fill portions are formed in the first-tier openings, and a second-tier structure can be formed over the first-tier structure. Memory openings including volumes of the first-tier memory openings are formed through the multi-tier structure, and memory stack structures are formed in the memory openings. Various contact openings are formed through the multi-tier structure, and various contact via structures are formed in the contact openings.

Claim (Index 14):
The three-dimensional memory device of  claim 13 , wherein:\n the first staircase-region contact via structures and the plate contact via structure comprise metallic liners that differ in at least in one of composition and thickness; and the plate contact via structure comprises a metallic liner continuously extending from a top surface of the conductive plate layer to the top surface of the second dielectric pillar structure and including a first horizontal jog region contacting the bottom surface of the second dielectric pillar structure, and a metal fill material portion filling a volume laterally surrounded by the metallic liner.
