• PVD sputtering target's introduction

  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.
