Novel processes for the fabrication of mesoscopic Josephson junction qubits have been developed, based on superconducting Al/Al2O3/Al tunnel junctions. These are fabricated by electron beam lithography using single-layer and multi-layer resists, and standard processes that are compatible with conventional CMOS processing. The new single-layer resist process is found to have significant advantages over conventional fabrication methods using suspended tri-layer shadow masks.
