Abstract
A microelectronic device comprises a stack structure, a staircase structure, an etch stop material, and insulative material. The stack structure comprises conductive structures, and air gaps vertically alternating with the conductive structures. The staircase structure is within the stack structure and has steps comprising edges of at least some of the conductive structures of the stack structure. The etch stop material continuously extends over the conductive structures and at least partially defines horizontal boundaries of the air gaps. The insulative material overlies the etch stop material. Additional microelectronic devices, memory devices, electronic systems, and methods are also disclosed.
