Abstract: Methods, systems, and devices for support structures for tier deflection in a memory system are described. The memory system may include a word line contact that extends through a stack of materials and lands on a tier of a word line. The word line contact may be between four support structures that form a diamond around the word line contact. Two support structures that form opposite vertices of the diamond may align centrally with the word line contact in a lateral direction and two other support structures that form opposite vertices of the diamond may align centrally with the word line contact in a longitudinal direction.

Abstract: A method of forming an apparatus includes forming pillar structures extending vertically through a first isolation material, forming conductive lines operatively coupled to the pillar structures, forming dielectric structures overlying the conductive lines, and forming air gaps between neighboring conductive lines. The air gaps are laterally adjacent to the conductive lines with a portion of the air gaps extending above a plane of an upper surface of the laterally adjacent conductive lines and a portion of the air gaps extending below a plane of a lower surface of the laterally adjacent conductive lines. Apparatuses, memory devices, methods of forming a memory device, and electronic systems are also disclosed.

Abstract: Some embodiments include an integrated assembly having a channel-material-pillar extending vertically through a stack of alternating conductive levels and insulative levels. The channel-material-pillar includes a first semiconductor material. A second semiconductor material is directly against an upper region of the channel-material-pillar. The second semiconductor material has a higher dopant concentration than the first semiconductor material and joins to the first semiconductor along an abrupt interfacial region such that there is little to no mixing of dopant from the second semiconductor material into the first semiconductor material. Some embodiments include methods of forming integrated assemblies.
