Abstract:
At least one diode, lower-level metal interconnect structures embedded within lower-level dielectric material layers, and a doped semiconductor material layer are formed over a semiconductor substrate. An electrically conductive path is provided between the at least one diode and the doped semiconductor material layer. An alternating stack of insulating layers and spacer material layers and memory stack structures extending therethrough are formed above the doped semiconductor material layer. A backside trench is formed through the alternating stack. The electrically conductive path is employed during plasma etch processes employed to form the memory stack structures and the backside trench to provide a discharge path for accumulated electrical charges. The electrically conductive path is subsequently disconnected by removing a conductive component underlying the backside trench. The spacer material layers can be replaced with electrically conductive layers employing the backside trench.

Claim (Index 11):
A method of forming a three-dimensional memory device, comprising:\n forming at least one diode over a substrate; forming at least one doped semiconductor material layer over the at least one diode, wherein the at least one diode is electrically connected to the at least one doped semiconductor material layer; forming an alternating stack of insulating layers and spacer material layers over the at least one doped semiconductor material layer; forming memory stack structures through the alternating stack; and etching a backside trench through the alternating stack, wherein an electrically conductive path between the at least one diode and the at least one doped semiconductor material layer is disconnected by the etching.
