Physical vapor deposition (PVD) is a thin-film preparation technique that physically vaporizes the surface of a target into gaseous atoms, molecules, or parts into ions under vacuum conditions. A film with a specific function is then deposited on the surface of the substrate via a low-pressure gas (or plasma). The main methods of physical vapor deposition include vacuum evaporation, sputtering deposition, arc plasma plating, ion plating, etc. Read More »

The target material​ is the material of making thin film, using the target material bombarded by high-speed charged particles, through different laser (ion beam) and different target material interaction to get different membrane system, to achieve the function of conduction and blocking. Therefore, the target is also called "sputtering target". His working principle is to use the ions generated by the ion source to gather and accelerate in vacuum Read More »
