  • Methods for fabricating a 3-dimensional memory structure of nor memory strings
    Patent number: 11751391
    Abstract: A process for building a 3-Dimensional NOR memory array avoids the challenge of etching a conductor material that is aimed at providing local word lines at a fine pitch. The process defines the local word lines between isolation shafts that may be carried out at a lower aspect ratio than would be required for etching the conductor material.
    Type: Grant
    Filed: July 21, 2021
    Date of Patent: September 5, 2023
    Assignee: SUNRISE MEMORY CORPORATION
    Inventors: Vinod Purayath, Yosuke Nosho, Shohei Kamisaka, Michiru Nakane, Eli Harari
