Classification: CPC H | IPC H

Claim 0:
1. 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;
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, the operative conductive vias and the dummy structures individually comprising a conductive core and an insulative periphery.
