  • Publication number: 20240349478
    Abstract: A method of forming a microelectronic device includes forming a first dielectric stack over a semiconductor base structure including pillar structures separated by filled isolation trenches. Digit line contacts are formed to partially vertically extend through the first dielectric stack and into digit line contact regions of the pillar structures. Digit lines are formed over and in contact with the digit line contacts, and partially vertically extend through the first dielectric stack. A second dielectric stack is formed over the digit lines and the first dielectric stack. Storage node contacts are formed to vertically extend partially through the second dielectric stack, completely through the first dielectric stack, and into storage node contact regions of the pillar structures. Redistribution layer structures are formed over and in contact with the storage node contacts, and partially vertically extend through the second dielectric stack.

  • Patent number: 11735473
    Abstract: Methods of manufacturing memory devices having memory cells and corresponding selectors, and associated systems and devices, are disclosed herein. In one embodiment, a method of manufacturing a memory device includes (a) removing a protection layer formed over the memory cells and (b) forming a cap layer over the memory cells before forming a conductive via through the memory device. The cap layer is configured to protect the memory cells during operation and can comprise a resistive material. The protection layer can be more efficiently removed with improved process margin and less device health impact using a polishing process before the conductive via is formed, thus increasing the manufacturing margin of the memory device.
