Tray 3 is located the shield ring 23 below, and on anchor clamps ring 4 detachable was fixed in tray 3, anchor clamps ring 4 was used for placing a wafer 10, and tray 3 can be the displacement from top to bottom. The target fixing devices 5 are disposed in the middle of the inner shield 21 and above the shield ring 23, the target fixing devices 5 are used for mounting and fixing the targets 20, and the number of the target fixing devices 5 in this embodiment is four.
During the production, the wafer 10 is placed in the clamp ring 4 and fixed, and at this time, the wafer 10 is located in the inner region 232 of the shield ring 23, and during the sputtering deposition reaction process, the material reacted by the target 20 is mainly deposited on the surface of the wafer 10 through the inner region 232 in the reaction region, and is partially deposited on a partial region of the clamp ring 4, the surface of the target fixing device 5 and the inner region of the shield 2, so that other parts of the contamination chamber are not affected. When the material deposited on the shield 2 reaches a certain level, the production can be continued by only removing the contaminated shield 2 and the clamp ring 4 from the chamber body 12 and replacing the new shield 2 and clamp ring 4, which can reduce the idle cost of the equipment, and simultaneously, the cleaning of the shield 2 and the clamp ring 4 is simpler than the cleaning of the whole chamber and the related cost is lower.
