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 9):
A three-dimensional memory device, comprising:\n an alternating stack of insulating layers and electrically conductive layers located over a sub state; drain-select-level electrically conductive strips located over the alternating stack, wherein each of the drain-select-level electrically conductive strips comprises a combination of at least one metallic material portion and a doped semiconductor spacer; a drain-select-level isolation structure located between a neighboring pair of drain-select-level electrically conductive strips; memory stack structures comprising a memory film and a vertical semiconductor channel vertically extending through the alternating stack and a respective one of the drain-select-level electrically conductive strips; and drain regions located on top of a respective one of the memory stack structures; wherein: the drain-select-level isolation structure generally extends along a first horizontal direction; and the drain-select-level isolation structure includes a pair of laterally alternating sequences of planar vertical sidewall segments and concave vertical sidewall segments that alternate along the first horizontal direction.
