[0037] Reference Figures 1-2As shown, an embodiment of this application discloses a cavity gate structure 100 for a magnetron sputtering machine. The cavity gate structure 100 of the magnetron sputtering machine includes a coating cavity 1, a fixed cover plate 2, and a movable cover plate 4. The coating cavity 1 includes a first end 11 and a second end 12 disposed opposite to each other. The fixed cover plate 2 is disposed at the first end 11 and is fixedly connected to the coating cavity 1 to seal the first end 11. The movable cover plate 4 is disposed at the second end 12 and is used to seal or open the coating cavity 1.
[0038] The coating cavity 1 is a cylindrical structure, with the first end 11 and the second end 12 representing the two ends of the cylindrical structure. Optionally, the coating cavity 1 can be a cylindrical or square tube, etc.
[0039] The magnetron sputtering machine cavity door structure 100 provided in this embodiment is equipped with a fixed cover plate 2 and a movable cover plate 4. The fixed cover plate 2 is disposed at the first end 11 of the coating cavity 1 and is fixedly connected to the coating cavity 1 to seal the coating cavity 1. The movable cover plate 4 is disposed at the second end 12 of the coating cavity 1 and is used to seal or open the coating cavity 1. In this way, there is no need to provide a movable space for the fixed cover plate 2, thereby saving factory space and helping to save costs.
[0040] Specifically, when it is necessary to open the coating chamber 1, the coating chamber 1 is opened by driving the movable cover plate 4 to move. After the coating chamber 1 is opened, the substrate can enter and exit the coating chamber 1 through the second end 12, and the cathode 3 can also enter and exit the coating chamber 1 through the second end 12, so as to realize the replacement and maintenance of the cathode 3.
[0041] Among them, the movable cover plate 4 can move along the axial direction of the coating cavity 1 (e.g., Figure 1 The cover plate 4 can be moved (in the direction of the middle arrow) to open or seal the coating cavity 1. In another embodiment, the movable cover plate 4 can be moved radially (perpendicular to) the coating cavity 1. Figure 1 The movable cover plate 4 (in the direction of the middle arrow) moves to open or seal the coating cavity 1. In another embodiment, the movable cover plate 4 can be rotatably connected to the coating cavity 1 via a pivot to open or seal the coating cavity 1.
[0042] Reference Figure 2 and 3 As shown, in one embodiment, the cavity structure 100 of the magnetron sputtering machine further includes a support component 5. The support component 5 is disposed within the coating cavity 1 and is connected to and supports the cathode 3 within the coating cavity 1. By using the support component 5 to support the cathode 3, deformation of the cathode 3 due to bending moment can be avoided, thus improving the long-term operational stability of the equipment.
[0043] In one embodiment, the support component 5 supports one end of the cathode 3, and the fixing cover plate 2 supports the other end of the cathode 3, preventing the cathode 3 from deforming due to bending moment. Simultaneously, since both ends of the cathode 3 are supported, the thickness of the fixing cover plate 2 can be significantly reduced, thereby saving costs and reducing equipment weight.

The support groove 521 supports the end of the cathode 3, facilitating the installation and removal of the cathode 3. Furthermore, the support groove 521 is an arc-shaped groove, which matches the shape of the end of the cathode 3, allowing for better positioning of the cathode 3.
[0045] Optionally, the support plate 51 is connected to the inner wall of the coating cavity 1 by bolts or screws. In other embodiments, the support plate 51 is directly welded to the inner wall of the coating cavity 1.
[0046] Reference Figure 4 As shown, in one embodiment, the bottom of the support block 52 is provided with a slot 522 that engages with the support plate 51. The connection between the support block 52 and the support plate 51 is achieved by engaging with the support plate 51 through the slot 522, which facilitates the installation and disassembly of the support block 52 and the support plate 51. At the same time, it is convenient to adjust the installation position of the support block 52 according to installation needs.
[0047] In one embodiment, the support assembly 5 includes multiple support plates 51 and multiple support blocks 52, with at least one support block 52 disposed on each support plate 51. Specifically, the coating cavity 1 is provided with multiple cathodes 3 arranged in a ring, and each support block 52 supports the corresponding cathode 3, thereby supporting and positioning all cathodes 3. Optionally, at least one support plate 51 may have one support block 52, or at least one support plate 51 may have multiple support blocks 52, such as two or three support blocks 52.
[0048] Reference Figure 1 and 2 As shown, in one embodiment, the cavity door structure 100 of the magnetron sputtering machine further includes a flange 6. The flange 6 is disposed between the movable cover plate 4 and the coating cavity 1. The flange 6 is fixedly connected to the coating cavity 1, and the movable cover plate 4 is detachably connected to the flange 6. The movable cover plate 4 is connected to the coating cavity 1 through the flange 6, which facilitates the installation and removal of the movable cover plate 4, while ensuring the sealing performance of the coating cavity 1.
[0049] In one embodiment, the coating cavity 1 and the flange 6 are connected by a fillet weld. A continuous weld mark is provided between the inner side of the coating cavity 1 and the flange 6, and an intermittent weld mark is provided between the outer side of the coating cavity 1 and the flange 6, so as to ensure the welding strength between the coating cavity 1 and the flange 6, and at the same time save welding materials.
