METHOD OF FABRICATING OXIDE SUPERCONDUCTING FILM

摘要

A laser beam (2) is applied to a target (1) of an oxide superconductive material, to deposit atoms and/or molecules which are scattered from the target (1) on a first portion (4) of a substrate (3) under an atmosphere containing oxygen for a start. Then, the substrate (3) is moved to deposit atoms and/or molecules scattered from the target (10) on a second portion, which is different form the first portion (4) of the substrate (3), under the atmosphere containing oxygen. At this time, the first portion (4) is subjected to oxygen annealing. These deposition steps are repeated until an oxide superconducting film of a desired thickness is obtained.
