    Abstract: Embodiments of the present disclosure describe removing seams and voids in metal interconnects and associated techniques and configurations. In one embodiment, a method includes conformally depositing a metal into a recess disposed in a dielectric material to form an interconnect, wherein conformally depositing the metal creates a seam or void in the deposited metal within or directly adjacent to the recess and heating the metal in the presence of a reactive gas to remove the seam or void, wherein the metal has a melting point that is greater than a melting point of copper. Other embodiments may be described and/or claimed.
