Abstract:
A method of fabricating a magnetic memory device, comprising;providing a workpiece having a plurality of first conductive lines formed thereon and a magnetic stack material disposed over the first conductive lines; depositing a thin conductive hard mask over the magnetic stack materials; patterning the thin conductive hard mask with a pattern after at least one magnetic memory cell; patterning the magnetic stack material with the at least one magnetic memory cell pattern to form at one magnetic memory cell; depositing a conductive material over the thin conductive hard mask; patterning the conductive material to form at least one conductive stud over the thin conductive hard mask, wherein the at least one conductive stud is fully landed on the thin conductive hard mask; and forming a plurality of second lines over the at least one conductive stud, the second conductive lines running in a different direction than the first conductive lines.
