Abstract

Magnetic Random Access memories sense their bit values by the measuring the resistance offered to a tunneling current. This requires contacting through a top electrode. We discuss a method of fabricating such an electrode in a fashion that could reduce damage to the magnetic stack and increase across-the-wafer homogeneity.
