Classification: CPC H | IPC H

Claim 16:
17. A device comprising:
an array of elevationally-extending transistors; and
a circuit structure adjacent and electrically coupled to the elevationally-extending transistors of the array, the circuit structure comprising:
a stair step structure comprising vertically-alternating tiers comprising conductive steps that are at least partially elevationally separated from one another by insulative material, one of the conductive steps comprising conductive material that extends into the array and which electrically couples to some of the transistors in the array, another of the conductive steps comprising conductive material that does not extend into the array and which does not electrically couple to any transistor in the array;
operative conductive vias individually extending elevationally through one of the conductive steps at least to a bottom of the vertically-alternating tiers and which individually electrically couple to an electronic component below the vertically-alternating tiers; and

dummy structures individually extending elevationally through one of the conductive steps at least to the bottom of the vertically-alternating tiers.
