Abstract: Conductive structures include stair step structures positioned along a length of the conductive structure and at least one landing comprising at least one via extending through the conductive structure. The at least one landing is positioned between a first stair step structure of the stair step structures and a second stair step structure of the stair step structures. Devices may include such conductive structures. Systems may include a semiconductor device and stair step structures separated by at least one landing having at least one via formed in the at least one landing. Methods of forming conductive structures include forming at least one via through a landing positioned between stair step structures.

Abstract: Microelectronic devices include stadium structures within a stack structure and substantially symmetrically distributed between a first pillar structure and a second pillar structure, each of which vertically extends through the stack structure. The stack structure includes a vertically alternating sequence of insulative materials and conductive materials arranged in tiers. Each of the stadium structures includes staircase structures having steps including lateral ends of some of the tiers. The substantially symmetrical distribution of the stadium structures, and fill material adjacent such structures, may substantially balance material stresses to avoid or minimize bending of the adjacent pillars. Related methods and systems are also disclosed.

Abstract: Apparatuses and methods for stair step formation using at least two masks, such as in a memory device, are provided. One example method can include forming a first mask over a conductive material to define a first exposed area, and forming a second mask over a portion of the first exposed area to define a second exposed area, the second exposed area is less than the first exposed area. Conductive material is removed from the second exposed area. An initial first dimension of the second mask is less than a first dimension of the first exposed area and an initial second dimension of the second mask is at least a second dimension of the first exposed area plus a distance equal to a difference between the initial first dimension of the second mask and a final first dimension of the second mask after a stair step structure is formed.
