Abstract

The invention discloses a functional film preparing method of molten substrate surface, which is characterized by the following: adopting the material of solid-phase low-melting point and low vapor pressure at ambient temperature; elevating substrate temperature before depositing film; melting film for liquid phantom background; evaporating film material atom and depositing to liquid level substrate surface with the method of magnetron sputtering or heat evaporation; adopting the method of diffusing, formatting the core, rolling, aggregating to grow functional film of characteristic grain arrangement; reducing substrate temperature to room temperature after finishing aggradation; curing background; keeping microconfiguration of film stable. The method simplifies technique, which reduces the cost.

Description

technical field [0001] The invention belongs to the technical field of preparation of nanoparticles, nanocrystal grains, high-strength adhesion between films and substrates, and functional films with characteristic microstructures, and specifically relates to a new film preparation technology: low melting point and low The vapor pressure material is the substrate; before depositing the film, the temperature of the substrate is raised to melt it into a liquid phase substrate; after the deposition is completed, the temperature of the substrate is freely cooled to room temperature, and the substrate is solidified, so that the microstructure of the film is maintained stably . Background technique [0002] In the past few decades, brilliant achievements have been made in thin film science and technology research, and new functional thin films with various unique functions emerge in an endless stream, such as the mature superconducting thin film in the 1970s, the superlattice thin...
