Abstract
Methods, systems, and devices for a barrier structure for preventing removal of, such as etching to, control circuitry are described. A memory device may include control circuitry over a substrate and for accessing a memory array and contact regions configured to couple with the control circuitry. The memory device may include barrier regions between respective contact regions that includes a barrier material. The memory device may include a stack of layers over the barrier region and the contact regions that is associated with the memory array, and the barrier material may prevent a removal (e.g., an etch) through the stack of layers and at least partially between contact regions from extending to the control circuitry.
