  • INTEGRATED WORD LINE CONTACT STRUCTURES IN THREE-DIMENSIONAL (3D) MEMORY ARRAY
    Publication number: 20230402389
    Abstract: A memory array including integrated word line (WL) contact structures are disclosed. The memory array comprises a plurality of WLs that includes at least a first WL and a second WL. An integrated WL contact structure includes a first WL contact and a second WL contact for the first WL and the second WL, respectively. The second WL contact extends through the first WL contact. For example, the second WL contact is nested within the first WL contact. An intervening isolation material isolates the second WL contact from the first WL contact. In an example, the second WL contact extends through a hole in the first WL to reach the second WL. The isolation material isolates the second WL contact from sidewalls of the hole in the first WL.
