This process is suitable for fabrication of extremely low-loss electrodes for capacitors, co-planar waveguides, and other similar structures used on, e.g., qubit chips. VTT has fabricated a large number of superconducting high-Qi resonators on these films, consistently reaching low-power Qi values of 0.5 to 1.5 million co-planar resonators with center frequencies in the range of 4 to 7 GHz and center pin (gap) width of 20 µm (10 µm). Specifications Standard chip sizes: 2.5 mm x 2.5 mm, 2.5 mm x 5.0 mm, 5.0 mm x 5.0 mm, 10 mm x 5.0 mm, 10 mm x 10 mm (others on case-by-case basis) Non-metallized area at chip perimeter: ≥ 50 µm Metallization line width: ≥ 1.0 µm Slit width: ≥ 0.8 µm Metallization line width reproducibility: ± 0.075 µm Metallization sheet resistance (at room temperature): ca. 1.1 Ω Metallization residual resistivity ratio (RRR): ca. 4
