Coating
In a vacuum environment, a vacuum coating machine heats and evaporates or sputters metallic or non - metallic materials, causing atoms or molecules to deposit on the surface of the wafer to form a thin film. Based on physical vapor deposition technology, it includes evaporation coating and sputtering coating. In the former, the coating material is heated and evaporated, and gaseous atoms are deposited in a vacuum. In the latter, high - energy particles are used to bombard the target material, causing atoms to sputter and deposit on the wafer. The equipment consists of a vacuum system, an evaporation or sputtering system, and a monitoring system. The vacuum system maintains a high - vacuum environment, the evaporation or sputtering system realizes the evaporation or sputtering of the coating material, and the monitoring system monitors coating parameters to ensure quality. This can improve the optical, electrical, and mechanical properties of the wafer and is applied in industries such as optics and electronics.
