Abstract:
A method of forming a three-dimensional memory device includes forming an alternating stack of insulating layers and sacrificial material layers over a substrate, forming a patterned template structure around memory openings in a drain-select-level above the alternating stack, forming drain-select-level isolation structures in trenches in the patterned template structure, forming memory stack structures in the memory openings extending through the alternating stack, where each of the memory stack structures includes a memory film and a vertical semiconductor channel, replacing the sacrificial material layers with word lines, and separately replacing the patterned template structure with a drain select gate electrode.

Claim (Index 23):
The method of  claim 20 , wherein the recess regions are formed by:\n forming a photoresist layer including openings therein over the sacrificial matrix layer; and anisotropically etching unmasked regions of the sacrificial matrix layer employing an etch chemistry that is selective to a material of the sacrificial pillar structures, wherein: a first subset of the sacrificial pillar structures protrudes within the recess regions; and a second subset of the sacrificial pillar structures contacts the remaining portions of the sacrificial material layer and has sidewalls that are physically exposed to a respective one of the recess regions.
