Abstract:
A semiconductor device structure comprises stacked tiers each comprising a conductive structure and an insulating structure longitudinally adjacent the at least one conductive structure, at least one staircase structure having steps comprising lateral ends of the stacked tiers, and an opening laterally adjacent a first side of the at least one staircase structure and extending through the stacked tiers and continuously across an entire length of the at least one staircase structure. Conductive structures of the stacked tiers laterally extend from the steps of the at least one staircase structure completely across a second side of the at least one staircase structure opposing the first side to form continuous conductive paths laterally extending completely across the stacked tiers. Additional semiconductor device structures, methods of forming semiconductor device structures, and electronic systems are also described.

Claim (Index 1):
A method of forming a semiconductor device structure, comprising:\n forming a stack structure comprising stacked tiers each comprising a conductive structure and an insulating structure longitudinally adjacent the conductive structure; forming a masking structure over a portion of the stack structure; removing portions of the stacked tiers of the stack structure not covered by the masking structure to form a secondary stack structure comprising at least one staircase structure having steps comprising lateral ends of the stacked tiers; removing the masking structure after forming the secondary stack structure; removing portions of the secondary stack structure to form a tertiary stack structure comprising:\n opposing end sections exhibiting a first width; \n an interior section laterally intervening between the opposing end sections and exhibiting a second width smaller than the first width, the interior section comprising at least one additional staircase structure exhibiting a smaller width than the at least one staircase structure of the secondary stack structure and an elongate middle region directly laterally adjacent a first side of the at least one additional staircase structure; and \n an opening laterally adjacent a second side of the at least one additional staircase structure opposing the first side and extending through the tertiary stack structure and continuously across an entire length of the at least one additional staircase structure, additional conductive structures of the tertiary stack structure laterally extending from additional steps of the at least one additional staircase structure and completely across the elongate middle region of the interior section; \n coupling at least one contact structure to one or more of the additional conductive structures of the tertiary stack structure at one or more of the additional steps of the at least one additional staircase structure; and forming at least one routing structure coupled to the at least one contact structure and extending from the at least one contact structure, through the opening, and to at least one string driver device.
