Conductive Structures, Assemblies Having Vertically-Stacked Memory Cells Over Conductive Structures, and Methods of Forming Conductive Structures

Abstract

Some embodiments include a conductive structure of an integrated circuit. The conductive structure includes an upper primary portion, with the upper primary portion having a first conductive constituent configured as a container. The container has a bottom, and a pair of sidewalls extending upwardly from the bottom. An interior region of the container is over the bottom and between the sidewalls. The upper primary portion includes a second conductive constituent configured as a mass filling the interior region of the container. The second conductive constituent is a different composition than the first conductive constituent. One or more conductive projections join to the upper primary portion and extend downwardly from the upper primary portion. Some embodiments include assemblies comprising memory cells over conductive structures. Some embodiments include methods of forming conductive structures.
