Original Abstract Submitted

superconducting solder bumps are produced on a qubit substrate by electrodeposition. the substrate comprises qubit areas, and superconducting contact pads connected to the qubit areas. first a protection layer is formed on the substrate, and patterned so as to cover at least the qubit areas. then one or more thin layers are deposited conformally on the patterned protection layer, the thin layers comprising at least a non-superconducting layer suitable for acting as a seed layer for the electrodeposition of the solder bumps. the seed layer is removed locally in areas which lie within the surface area of respective contact pads. this is done by producing and patterning a mask layer, so that openings are formed therein, and by removing the seed layer from the bottom of the openings. the solder bumps are formed by electrodeposition of the solder material on the bottom of the openings. after the formation of the solder bumps, the seed layer and the protection layer are removed.
