Abstract
Fabrication of a magnetic memory element, including a via () in an interlevel dielectric layer (), providing an electrical connection between an underlying metal region () and a magnetoresistive stack device, such as a magnetic tunnel junction (), involves forming a transition metal layer () in the via by atomic layer deposition. The via optionally includes a tantalum-rich layer () above, and/or a cap layer () below, the transition metal layer, and may have a diameter less than or equal than a diameter of the magnetoresistive stack device.
