Method of Fabricating A-Axis Josephson Junctions

A method for fabricating a Josephson Junction, the method comprising:

• forming at least one trilayer monolith from a trilayer, wherein the trilayer comprises a top HTS layer, an insulator layer, and a bottom HTS layer, wherein the top HTS layer and the bottom HTS layer comprise a high-temperature superconducting (“HTS”) material, wherein the HTS material is an a-axis HTS material, wherein the trilayer monolith is formed by removing a portion of the top HTS layer and a portion of the insulator layer to expose the bottom HTS layer;
• forming at least one wire in the bottom HTS layer by removing a portion of the bottom HTS layer;
• growing a second insulator layer over the at least one trilayer monolith formed from the trilayer and the at least one wire formed in the bottom HTS layer;
• forming at least one via hole in the second insulator layer to reveal at least one component underlying the second insulator layer, wherein the underlying component comprises either the top HTS layer of the at least one trilayer monolith or the at least one wire formed in the bottom HTS layer;
• growing a top HTS wiring layer over the second insulator and the underlying component, wherein the top HTS wiring layer comprises an HTS material;
• and
• forming at least one wire in the top HTS wiring layer.
