    Abstract: A structure is provided that includes a first active circuit in which at least one of areas surrounding the first active circuit includes an active circuit-containing region. A second active circuit is spaced apart from the first active circuit. The second active circuit includes a circuit mimic fill area present in at least one of the areas surrounding the second active circuit. The circuit mimic fill area substantially matches the active circuit-containing region that is adjacent to the first active circuit.

  • Patent number: 12193341
    Abstract: Methods, systems, and devices for low resistance via contacts in a memory device are described. A via may be formed so as to protrude from a surrounding material. A barrier material may be formed above an array area and also above the via. After a first layer of an access line material is formed above the barrier material, a planarization process may be applied until the top of the via is exposed. The planarization process may remove the access line material and the barrier material from above the via, but the access line material and the barrier material may remain above the array area. The first layer of the access line material may protect the unremoved barrier material during the planarization process. A second layer of the access line material may be formed above the first layer of the access line material and in direct contact with the via.
