Abstract:
A three-dimensional memory device includes semiconductor devices located on a semiconductor substrate, lower interconnect level dielectric layers embedding lower interconnect structures, an alternating stack of insulating layers and electrically conductive layers overlying the lower interconnect level dielectric layers and including stepped surfaces, memory stack structures vertically extending through the alternating stack, and contact via structures extending downward from the stepped surfaces through underlying portions of the alternating stack to the lower interconnect structures. Each of the contact via structures laterally contacts an electrically conductive layer located at the stepped surfaces, and provides electrical interconnection to an underlying semiconductor device. A top portion of each contact via structures contacts an electrically conductive layer, and is electrically isolated from other underlying electrically conductive layers.

Claim (Index 17):
The method of  claim 16 , wherein:\n each of the contact via cavities has a top periphery that is adjoined to a respective horizontal surface of the stepped surfaces; a sidewall of a sacrificial material layer is physically exposed within each of the contact via cavities after formation of the metallic nitride liners and the metal fill portions; the method further comprises forming metallic pillar structures in unfilled volumes of each of the contact via cavities and directly on the sidewalls of the sacrificial material layers around the contact via cavities; and the metallic pillar structures are formed by a selective metal deposition process that grows a metallic material from surfaces of the metallic nitride liners and the metal fill portions and does not grow the metallic material from surfaces of the insulating layers and the sacrificial material layers.
