◇ What is a sputtering target?
Thin films with distinctive functions are used in the products around us, such as displays such as smartphones and LCD TVs, energy such as solar cells and lithium batteries, and recording media such as DVDs and hard disks.
In order to make such a thin film, applications such as sputtering, vapor deposition, ion plating, CVD (vapor phase growth method), which is a dry (vacuum) film forming method, and plating, spin coating, which is a wet film forming method, etc. Various processes have been developed by.
Among them, sputtering is a method that can form a uniform film over a large area, and is the mainstream for thin film production not only in the research and development field but also in mass production in factories. The general spattering procedure is as follows.
(1) Place the film-forming material (metal, alloy, oxide, etc.) on one side of the vacuum chamber and the substrate on the other side.
(2) When a high voltage is applied to the vacuum chamber and ionized argon or the like hits the film-forming material at high speed,
(3) the atom of the material pops out from there and reaches the substrate to grow a thin film and form a film. Is completed.
