Abstract:
A method of forming a semiconductor device structure comprises forming a stack structure comprising stacked tiers. Each of the stacked tiers comprises a first structure comprising a first material and a second structure comprising a second, different material longitudinally adjacent the first structure. A patterned hard mask structure is formed over the stack structure. Dielectric structures are formed within openings in the patterned hard mask structure. A photoresist structure is formed over the dielectric structures and the patterned hard mask structure. The photoresist structure, the dielectric structures, and the stack structure are subjected to a series of material removal processes to form apertures extending to different depths within the stack structure. Dielectric structures are formed over side surfaces of the stack structure within the apertures. Conductive contact structures are formed to longitudinally extend to bottoms of the apertures. Semiconductor device structures, semiconductor devices, and electronic systems are also described.

Claim (Index 1):
A three-dimensional memory device, comprising:\n a stack structure comprising longitudinally alternating conductive structures and insulating structures, the stack structure free of stair step structures at lateral ends thereof; conductive contact structures within filled apertures in the stack structure and each individually in physical contact with the one of the conductive structures of the stack structure; vertical strings of memory cells extending through the stack structure; and a control device underlying the stack structure and electrically coupled to the conductive contact structures.
