Assignee: nan
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A method of forming an integrated assembly, comprising:
forming a first stack comprising a second material over a first material, the first material being electrically conductive;
doping second regions of the second material while leaving first regions of the second material undoped; the first regions extending laterally around the second regions;
forming a second stack over the first stack; the second stack having alternating first and second levels;
forming first openings to extend through the first and second stacks;
forming cell materials within the first openings to line the first openings, the cell materials including charge-storage material and insulative material;
forming channel material within the lined first openings and spaced from the charge-storage material by the insulative material;
forming a second opening to pass through the second stack and to one of the first regions of the second material;
removing the first regions selectively relative to the second regions; the removing of the first regions forming conduits that pass around the second regions, and that pass from the second opening to the cell materials;
extending the conduits through the cell materials and to the channel material;
forming doped semiconductor material within the extended conduits;
out-diffusing dopant from the doped semiconductor material into the channel material, the out-diffused dopant extending upwardly to at least one of the first levels; and
forming conductive material within the first levels.
