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.

A microelectronic device comprises a stack structure comprising alternating conductive structures and insulative structures arranged in tiers, each of the tiers individually comprising a conductive structure and an insulative structure, strings of memory cells vertically extending through the stack structure, the strings of memory cells comprising a channel material vertically extending through the stack structure, and another stack structure vertically overlying the stack structure and comprising other tiers of alternating levels of other conductive structures and other insulative structures, the other conductive structures exhibiting a conductivity greater than a conductivity of the conductive structures of the stack structure. Related memory devices, electronic systems, and methods are also described.

A microelectronic device comprises a stack structure comprising a stack structure comprising a vertically alternating sequence of conductive structures and insulative structures arranged in tiers, the stack structure divided into block structures separated from one another by slot structures, strings of memory cells vertically extending through the block structures of the stack structure, the strings of memory cells individually comprising a channel material vertically extending through the stack structure, an additional stack structure vertically overlying the stack structure and comprising a vertical sequence of additional conductive structures and additional insulative structures arranged in additional tiers, first pillars extending through the additional stack structure and vertically overlying the strings of memory cells, each of the first pillars horizontally offset from a center of a corresponding string of memory cells, second pillars extending through the additional stack structure and vertically overlying the strings of memory cells, and additional slot structures comprising a dielectric material extending through at least a portion of the additional stack structure and sub-dividing each of the block structures into sub-block structures, the additional slot structures horizontally neighboring the first pillars. Related microelectronic devices, electronic systems, and methods are also described.

Some embodiments include an assembly having channel-material-structures, and having memory cells along the channel-material-structures. The memory cells include charge-storage-material. Linear-conductive-structures are vertically offset from the channel-material-structures and are electrically coupled with the channel-material-structures. Intervening regions are between the linear-conductive-structures. Conductive-shield-structures are within the intervening regions. The conductive-shield-structures are electrically coupled with a reference-voltage-source.

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.

Systems and methods for chemical mechanical planarization topography control via implants are disclosed. In one embodiment, a method of manufacturing a semiconductor device includes increasing the content of at least one of silicon or germanium in at least select regions of a dielectric material thereby reducing the material removal rate for a chemical mechanical polishing (CMP) process at the select regions, and removing material from the dielectric material using the CMP process. In another embodiment, a method of manufacturing a semiconductor device includes increasing content of at least one of boron, phosphorus, or hydrogen in at least select regions of a dielectric material thereby increasing the material removal rate of a CMP process at the select regions, and removing material from the dielectric material using the CMP process.
