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 3):
The three-dimensional memory device of  claim 1 , wherein:\n each of the contact via structures vertically extends through openings in each layer of the alternating stack that underlies the respective one of the electrically conductive layers; and each of the contact via structures is electrically isolated from each layer of the alternating stack that underlies the respective one of the electrically conductive layers by an insulating tubular liner.
