METHODS FOR FORMING MEMORY DEVICES, AND ASSOCIATED DEVICES AND SYSTEMS
Last updated:
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.
