    Abstract: Described herein are structures that include Josephson Junctions (JJs) to be used in superconducting qubits of quantum circuits disposed on a substrate. The JJs of these structures are fabricated using an approach that can be efficiently used in large scale manufacturing, providing a substantial improvement with respect to conventional approaches which include fabrications steps which are not manufacturable. In one aspect of the present disclosure, the proposed approach includes providing a patterned superconductor layer over a substrate, providing a layer of surrounding dielectric over the patterned superconductor layer, and providing a via opening in the layer of surrounding dielectric over a first portion of the patterned superconductor layer. The proposed approach further includes depositing in the via opening a first superconductor, a barrier dielectric, and a second superconductor to form, respectively, a base electrode, a tunnel barrier layer, and a top electrode of the JJ.

    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.
