Abstract

The invention belongs to the technical field of thin film preparation, and particularly relates to a heating device for high-temperature thin film deposition. The heating device comprises two electrode assemblies, wherein current I is led onto a metal substrate base band from two edges of the metal substrate base band through electrodes and flows on the metal substrate base band; the metal substrate base band (Hastelloy with high electrical resistivity and the like) is heated up under the action of self resistance to reach the temperature required for YBCO growth; and a deposition area is positioned between the two electrode assemblies. The heating device is simple in principle and structure, quick in heating and high in energy efficiency, can be used for heating a banded metal substrate or a banded metal substrate on which a (conductive or insulating) buffer layer is prepared, and can realize continuous winding preparation of single-faced or double-faced YBCO long strips through eliminating discharge caused by poor contact between the electrodes and the base band.

Description

technical field [0001] The invention belongs to the technical field of thin film preparation, and in particular relates to the preparation of thin films in a high-temperature environment on a stationary or moving long strip-shaped metal substrate, which can be used in thin film preparation processes such as sputtering, evaporation, PLD, and MOCVD, and is specifically a method for high-temperature thin films. Deposition heating device. Background technique [0002] In the field of thin film preparation, in order to realize the controlled growth of the thin film, and then achieve the purpose of controlling the physical and chemical properties of the thin film, it is usually necessary to heat the substrate on which the thin film grows. [0003] Many manufacturers and research institutes are concentrating on designing more superior reaction chambers. To match the design of the reaction chamber, the heater must also be improved accordingly. Since the gas reaction in the chamber ...
