摘要:
This invention relates to an apparatus and method for forming a high temperature superconducting film on a tape substrate. In this invention, the superconducting film is deposited on the tape substrate wound around a cylindrical substrate holder inserted in an auxiliary chamber. The holder rotates during the whole deposition process. Vapors of film materials are supplied from a main chamber through an opening between the two chambers. According to the present invention, it is possible to form a highly uniform high temperature superconducting film on a tape substrate at high speeds suitable for large scale production. The manufacturing speed can easily be controlled by the size of the substrate holder.
摘要:
Disclosed herein is a method of fabricating a high temperature superconducting film in a vacuum chamber through auxiliary cluster beam spraying using an evaporation method, wherein a high temperature superconducting material is deposited on a substrate in a vapor state by evaporating the high temperature superconducting material, and at the same time, a cluster beam material is formed into gas atoms by heating the cluster beam material charged in a housing, and the formed gas atoms pass through a nozzle of an inlet of the housing and then are sprayed and grown on the substrate in the form of the cluster beam, thereby forming pinning centers in the high temperature superconducting film.
