Abstract

Method of forming a magnetic memory device are disclosed. In one embodiment, a first plurality of conductive lines are formed over a semiconductor workpiece. A plurality of magnetic material lines are formed over corresponding ones of the first plurality of conductive lines and a second plurality of conductive lines are formed over the semiconductor workpiece. The second plurality of conductive lines cross over the first conductive lines and the magnetic material lines. These second lines can be used as a mask to while the magnetic material lines are patterned.
