SHUTTER DISK FOR PHYSICAL VAPOR DEPOSITION (PVD) CHAMBER

Methods and apparatus reduce defects in substrates processed in a physical vapor (PVD) chamber. In some embodiments, a method for cleaning a process kit disposed in an inner volume of a process chamber includes positioning a non-sputtering shutter disk on a substrate support of the PVD chamber; ener...

Beschreibung
Zusammenfassung:	Methods and apparatus reduce defects in substrates processed in a physical vapor (PVD) chamber. In some embodiments, a method for cleaning a process kit disposed in an inner volume of a process chamber includes positioning a non-sputtering shutter disk on a substrate support of the PVD chamber; energizing an oxygen-containing cleaning gas disposed in the inner volume of the PVD chamber to create a plasma reactive with carbon-based materials; and heating the process kit having a carbon-based material adhered thereto while exposed to the plasma to remove at least a portion of the carbon-based material adhered to the process kit.
