1、 The basic principle of preparing nano Cu thin films by magnetron sputtering method

Magnetron sputtering is a physical vapor deposition technique that uses high-energy ions to bombard the surface of a target material, causing atoms or molecules of the target material to escape from the surface and deposit on a substrate to form a thin film. When preparing nano Cu thin films, high-purity copper targets are placed in a sputtering chamber, and inert gases (such as argon) are introduced and an electric field is applied to ionize the argon gas and produce argon ions. These high-speed moving argon ions bombard the surface of copper targets, sputtering copper atoms and depositing them on the substrate to form nanoscale thin films.
