Claim 10:
11. A method of forming a microelectronic device, the method comprising:
forming a first stack structure comprising alternating levels of insulative structures and other insulative structures;
forming strings of memory cells comprising at least a dielectric material and a channel material vertically extending through the first stack structure;
forming a second stack structure comprising alternating levels of additional insulative structures and additional other insulative structures vertically overlying the first stack structure;
forming first pillars extending through the second stack structure and vertically overlying first strings of memory cells of the strings of memory cells, a center of each of the first pillars horizontally offset from a center of a corresponding string of memory cells;
forming second pillars extending through the second stack structure and vertically overlying second strings of the strings of memory cells, a center of the each of the second pillars substantially horizontally aligned with a center of a corresponding string of memory cells;
forming a slot structure horizontally neighboring the first pillars, the slot structure comprising a horizontal dimension greater than a horizontal distance between one of the first strings of memory cells and one of the second strings of memory cells; and
replacing the other insulative structures and the additional other insulative structures through the slot structure to form respective conductive structures and additional conductive structures.
