Abstract

See full text

Vertical memory blocks for semiconductor devices include a memory cell region including an array of memory cell pillars and at least one via region including a dielectric stack of alternating dielectric materials and at least one conductive via extending through the dielectric stack. Semiconductor devices including a vertical memory block include at least one vertical memory block, which includes slots extending between adjacent memory cells of a three-dimensional array. The slots are separated by a first distance in a first portion of the block, and by a second, greater distance in a second portion of the block. Methods of forming vertical memory blocks include forming slots separated by a first distance in a memory array region and by a second, greater distance in a via region. At least one conductive via is formed through a stack of alternating first and second dielectric materials in the via region.
