Magnetoresistive random-access memory cell having a metal line connection
Abstract:
A method of fabricating an MRAM device, the method including forming a magnetoresistive random-access memory (MRAM) stack comprising a first hard mask, forming sidewall spacers adjacent to the MRAM stack, forming a layer of interconnect metal around and above the MRAM stack, recessing the interconnect metal, forming a layer of a second hard mask over the interconnect metal, and patterning and etching the second hard mask and interconnect metal, forming interconnect metal lines.
