Claim 9:
10. A method of manufacturing a bottom-pinned spin-orbit torque magnetic random access memory, comprising:
providing a substrate;
forming a bottom electrode layer, a pinned layer, a reference layer, a free layer, a spin-orbit torque layer and a capping layer sequentially on said substrate;
performing a photolithography process to pattern said bottom electrode layer, said pinned layer, said reference layer, said free layer, said spin-orbit torque layer and said capping layer into a memory unit;
forming an injection layer on said capping layer;
performing another photolithography process to pattern said injection layer into individual first part and second part, wherein said first part and said second part are connected respectively with two ends of said capping layer; and
forming an insulating layer between said first part and said second part, wherein a top surface of said insulating layer is flush with top surfaces of said first part and said second part of said injection layer.
