Spin-orbit torque (SOT) magnetoresistive random-access memory (MRAM) with low resistivity spin hall effect (SHE) write line

Abstract

Embodiments of the invention include a method for fabricating a magnetoresistive random-access memory (MRAM) structure and the resulting structure. A first type of metal is formed on an interlayer dielectric layer with a plurality of embedded contacts, where the first type of metal exhibits spin Hall effect (SHE) properties. At least one spin-orbit torque (SOT) MRAM cell is formed on the first type of metal. One or more recesses surrounding the at least one SOT-MRAM cell are created by recessing exposed portions of the first type of metal. A second type of metal is formed in the one or more recesses, where the second type of metal has lower resistivity than the first type of metal.
