  • Patent number: 11990367
    Abstract: An apparatus comprises a structure including an upper insulating material overlying a lower insulating material, a conductive element underlying the lower insulating material, and a conductive material comprising a metal line and a contact. The conductive material extends from an upper surface of the upper insulating material to an upper surface of the conductive element. The structure also comprises a liner material adjacent the metal line. A width of an uppermost surface of the conductive material of the metal line external to the contact is relatively less than a width of an uppermost surface of the conductive material of the contact. Related methods, memory devices, and electronic systems are disclosed.

  • Patent number: 11984382
    Abstract: Methods, systems, and devices related to a memory device with a thermal barrier are described. The thermal barrier (e.g., a low density thermal barrier) may be positioned between an access line (e.g., a digit line or a word line) and a cell component. The thermal barrier may be formed on the surface of a barrier material by applying a plasma treatment to the barrier material. The thermal barrier may have a lower density than the barrier material and may be configured to thermally insulate the cell component from thermal energy generated in the memory device, among other benefits.
