Self-aligned wire for spintronic device

Abstract

A method for fabricating a spintronic cell includes forming a cavity in a substrate, forming a wire in the cavity, depositing a spacer layer over exposed portions of the substrate and the conductive field line, depositing a layer of conductive material on a portion of the spacer layer, removing portions of the layer of conductive material to define a conductive strap portion, wherein the conductive strap portion has a first distal region a second distal region and a medial region arranged therebetween, wherein the medial region has a cross sectional area that is less than a cross sectional area of the first distal region and a cross sectional area of the second distal region, and forming an spintronic device stack on the conductive strap portion above the conductive field line.
