The technique of ''shadow evaporation'' has been used to fabricate superconducting-normal-superconducting Josephson microbridges and SQUID's with bridge widths of about 0.2 mm and lengths of 0.1 mm or less. The devices consist of vanadium banks and gold bridges and have static current-voltage characteristics that are consistent with the resistively shunted junction model down to at least 0.4 T/sub C/. Refined versions of this technique may be useful for batch fabrication of single and multibridge Josephson devices.
