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 19):
The method of  claim 18 , further comprising forming a conductive material portion having a same material composition as, and a same thickness as, the conductive plate layer concurrently with formation of the conductive plate layer,\n wherein:\n the conductive material portion is a topmost component of the subset of the lower-level metal interconnect structures that electrically shorts the at least one doped semiconductor material layer to the at least one diode and is laterally spaced from the conductive plate layer; and \n the etch process disconnects the electrically conductive path by removing a portion of the at least one doped semiconductor material layer located between the conductive plate layer and the conductive material portion.
