Memory Arrays Comprising Strings Of Memory Cells And Methods Used In Forming A Memory Array Comprising Strings Of Memory Cells

Last updated:

Abstract:

A method used in forming a memory array comprising strings of memory cells comprises forming a stack comprising vertically-alternating first tiers and second tiers. A channel-material string is in individual channel openings in the vertically-alternating first tiers and second tiers. A conductor-material contact is in the individual channel openings directly against the channel material of individual of the channel-material strings. The conductor-material contacts are vertically recessed in the individual channel openings. A conductive via is formed in the individual channel openings directly against the vertically-recessed conductor-material contact in that individual channel opening. Other aspects, including structure independent of method, are disclosed.
