Abstract
A method is provided for producing superconducting Josephson devices using a chemical etching solution which comprises forming a mask on a predetermined portion of a MgO substrate, and immersing the MgO substrate having the mask in an aqueous acid solution in which the volume ratio of phosphoric acid to sulfuric acid is approximately 10:1 or more, so as to form a step at the boundary between the masked region and the unmasked region.
