Abstract:
In a particular embodiment, a method of forming a magnetic tunnel junction (MTJ) device includes applying a dielectric layer to a surface, applying a metal layer to the dielectric layer, and adding a cap layer on the dielectric layer. The method also includes forming a magnetic tunnel junction (MTJ) stack such that an electrode of the MTJ stack is disposed on the metal layer and the cap layer contacts a side portion of the metal layer. An adjustable depth to via may connect a top electrode of the MTJ stack to a top metal.
