Abstract:
A three-dimensional memory device includes an alternating stack of insulating layers and word-line-level electrically conductive layers located over a substrate, and a drain-select-level electrically conductive layer located over the alternating stack. Memory stack structures extend through the alternating stack and the drain-select-level electrically conductive layer. Dielectric divider structures including a respective pair of straight sidewalls and drain-select-level isolation structures including a respective pair of sidewalls that include a respective set of concave vertical sidewall segments divide the drain-select-level electrically conductive layer into multiple strips. The drain-select-level electrically conductive layer and the drain-select-level isolation structures are formed by replacement of a drain-select-level sacrificial material layer with a conductive material and by replacement of drain-select-level sacrificial line structures with dielectric material portions.

Claim (Index 13):
The method of  claim 12 , further comprising:\n simultaneously depositing at least one conductive material in the drain-select-level backside recesses and peripheral regions of the drain-select-level isolation trenches; and anisotropically etching the at least one conductive material, wherein remaining portions of the at least one conductive material constitute the multi-level drain select electrodes.
