Abstract:
1. A method of fabricating a Josephson junction, the method comprising: depositing a first dielectric layer; planarizing a surface of the first dielectric layer; depositing a first electrode that superconducts at or below a critical temperature over at least a portion of the planarized surface of the first dielectric layer; forming an electrically insulative layer over at least a portion of the first electrode; depositing a second electrode that superconducts at or below the critical temperature over at least a portion of the electrically insulative layer; depositing an additional dielectric layer over at least a portion of the second electrode; planarizing a surface of the additional dielectric layer; forming a hole in the additional dielectric layer to expose at least a portion of the second electrode; and at least partially filling the hole in the additional dielectric layer with a material that superconducts at or below the critical temperature.
