Abstract
A method and device for preparing a Josephson junction are provided. The method includes: preparing a photoresist film layer comprising an undercut structure on a substrate, the undercut structure comprising a first strip-shaped opening and a second strip-shaped opening; performing, at a first angle, evaporation on the photoresist film layer obliquely to the substrate, to prepare a first strip-shaped superconducting layer through the first strip-shaped opening; and performing, at a second angle, evaporation on the photoresist film layer obliquely to the substrate, to prepare a second strip-shaped superconducting layer through the second strip-shaped opening, the first strip-shaped superconducting layer and the second strip-shaped superconducting layer crossing each other, and an intersection of the first strip-shaped superconducting layer and the second strip-shaped superconducting layer being isolated by an oxidation layer to form a Josephson junction.
