Abstract:
A method of forming circuitry components includes forming a stack of horizontally extending and vertically overlapping features. The stack has a primary portion and an end portion. At least some of the features extend farther in the horizontal direction in the end portion moving deeper into the stack in the end portion. Operative structures are formed vertically through the features in the primary portion and dummy structures are formed vertically through the features in the end portion. Horizontally elongated openings are formed through the features to form horizontally elongated and vertically overlapping lines from material of the features. The lines individually extend from the primary portion into the end portion, and individually laterally about sides of vertically extending portions of both the operative structures and the dummy structures. Sacrificial material that is elevationally between the lines is at least partially removed in the primary and end portions laterally between the horizontally elongated openings. Other aspects and implementations are disclosed.

Claim (Index 60):
A stack of horizontally extending and vertically overlapping features, the stack comprising:\n a primary portion and an end portion, at least some of the features extending farther in the horizontal direction in the end portion moving deeper into the stack in the end portion; operative structures extending vertically through the features in the primary portion, the operative structures comprising portions of memory cells, the memory cells comprising a portion of NAND architecture, the operative structures comprising interconnected channel regions of a NAND string, the at least some of the features comprising control gate lines; dummy structures extending vertically through the control gate lines in the end portion, some of the dummy structures being longitudinally spaced alone a horizontal line; and vertical contacts in the end portion connecting with individual of the control gate lines, at least one of the vertical contacts being longitudinally between two immediately-longitudinally adjacent of the dummy structures in the horizontal line.
