Abstract
Disclosed is a three-dimensional memory device. In one embodiment, a device is disclosed comprising a source plate; plugs fabricated fabricated on or partially formed in the source plate; a stack formed on the substrate and plugs comprising alternating insulating layers and conductive layers and channel-material strings of memory cells extending through the insulating layers and conductive layers; a first set of pillars extending through the stack formed by a process including etching the alternating insulating layers and conductive layers and depositing a pillar material therein, wherein each pillar in the first set of pillars terminates atop a respective plug in the plurality of plugs; and a second set of pillars extending through the stack formed by a process including etching the alternating insulating layers and conductive layers and depositing a pillar material therein, wherein each pillar in the second set of pillars terminates in the source plate.
