Abstract: Embodiments herein relate to magnetically doping a spin orbit torque electrode (SOT) in a magnetic random access memory apparatus. In particular, the apparatus may include a free layer of a magnetic tunnel junction (MTJ) coupled to a SOT electrode that is magnetically doped to apply an effective magnetic field on the free layer, where the free layer has a magnetic polarization in a first direction and where current flowing through the magnetically doped SOT electrode is to cause the magnetic polarization of the free layer to change to a second direction that is substantially opposite to the first direction.

Abstract: Trench contact structures with etch stop layers, and methods of fabricating trench contact structures with etch-stop layers, are described. In an example, an integrated circuit structure includes a fin structure. An epitaxial source or drain structure is on the fin structure. An isolation structure is laterally adjacent to sides of the fin structure. A dielectric layer is on at least a portion of a top surface of the isolation structure and partially surrounds the epitaxial source or drain structure and leaves an exposed portion of the epitaxial source or drain structure. A conductive trench contact structure is on the exposed portion of the epitaxial source or drain structure. The conductive trench contact structure does not extend into the isolation structure.
