Patent ID: 11929323
Assignee: MICRON TECHNOLOGY, INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 2:
3. The method of claim 1, wherein forming a microelectronic device structure comprises:
forming a preliminary stack structure over the doped semiconductive material, the preliminary stack structure comprising a vertically alternating sequence of first insulative structures and second insulative structures;
forming openings vertically extending through the preliminary stack structure and the doped semiconductive material and into the base structure;
forming the cell pillar structures within the openings;
forming slots extending through the preliminary stack structure;
at least partially replacing the second insulative structures with the conductive structures using the slots to form the stack structure, the insulative structures of the stack structure comprising remaining portions of the first insulative structures; and
forming the digit line structures over and in electrical communication with the cell pillar structures.
