Abstract
A semiconductor structure includes a memory die bonded to a logic die. The memory die includes an alternating stack of insulating layers and electrically conductive layers, a semiconductor material layer located on a distal surface of the alternating stack, a dielectric spacer layer located on a distal surface of the semiconductor material layer, memory opening fill structures vertically extending through the alternating stack, through the semiconductor material layer, and at least partly through the dielectric spacer layer, and a source layer located on a distal surface of the dielectric spacer layer and contacting pillar portions of the vertical semiconductor channels that are embedded within the dielectric spacer layer.
