  • Publication number: 20250087536
    Abstract: A deposition system provides a feature that may reduce costs of the sputtering process by increasing a target change interval. The deposition system provides an array of magnet members which generate a magnetic field and redirect the magnetic field based on target thickness measurement data. To adjust or redirect the magnetic field, at least one of the magnet members in the array tilts to focus on an area of the target where more target material remains than other areas. As a result, more ion, e.g., argon ion bombardment occurs on the area, creating more uniform erosion on the target surface.
