Abstract
A method to fabricate an MTJ device and its connections to a CMOS integrated circuit is described. The device is built out of three layers. The bottom layer serves as a seed layer for the center layer, which is alpha tantalum, while the third, topmost, layer is selected for its smoothness, its compatibility with the inter-layer dielectric materials, and its ability to protect the underlying tantalum.
