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 20):
The method of  claim 13 , further comprising:\n forming through-dielectric contact via structures on a respective one of the lower interconnect structures within an area outside of the alternating stack; and forming upper interconnect level dielectric layers embedding upper interconnect structures over the alternating stack, wherein: the upper interconnect structures comprise bit lines that are electrically shorted to an upper end of a respective one of the vertical semiconductor channels and to a respective one of the through-dielectric contact via structures; and the semiconductor devices comprise bit line drivers.
