    Abstract: A thin-film deposition system includes a thin-film deposition chamber. A magnetron assembly is positioned within the thin-film deposition chamber to assist in thin-film deposition processes. A magnetic sensor apparatus is positioned adjacent to the magnetron assembly. The magnetic sensor apparatus includes a plurality of magnetic sensors that each sense the magnetic field in a particular location within the thin-film deposition chamber. The control system generates a magnetic field distribution based on the sensor signals from the magnetic sensors. An analysis model that has been trained with a machine learning process analyzes the magnetic field distribution and determines whether or not an abnormal magnetic field distributions process. The control system can stop the thin-film deposition process based on the output of the analysis model.

    Abstract: A deposition system is provided capable of controlling an amount of a target material deposited on a substrate and/or direction of the target material that is deposited on the substrate. The deposition system in accordance with the present disclosure includes a substrate process chamber. The deposition includes a substrate pedestal in the substrate process chamber, the substrate pedestal configured to support a substrate, a target enclosing the substrate process chamber, and a collimator having a plurality of hollow structures disposed between the target and the substrate, wherein a length of at least one of the plurality of hollow structures is adjustable.

    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.
