Technical Field
[0001] The utility model relates to the technical field related to PVD equipment, and in particular to a device for facilitating the replacement of target materials. Background Art
[0002] PVD physical vapor deposition technology refers to the technology of using physical methods under vacuum conditions to vaporize the surface of the material source (solid or liquid) into gaseous atoms or molecules, or partially ionize it into ions, and deposit a thin film with certain special functions on the surface of the substrate through a low-pressure gas (or plasma) process. Physical vapor deposition is one of the main surface treatment technologies.
[0003] After massive searches, it was found that the prior art publication number is CN212025441U, which discloses a combined PVD coating target and a PVD coating machine. The combined PVD coating target includes a target body and a base of different materials. The target body and the base are separately arranged, and the first end of the base is connected to one end of the target body, so that the base and the target body are combined into one. The combined PVD coating target of the utility model can solve the problem that the brittle target of the prior art is easy to break when it is installed and matched with the coating machine, which helps to improve the film quality, improve production efficiency and reduce costs.
[0004] To sum up, after a period of use, the target material on the existing magnetron sputtering device will become uneven on its surface under the action of inert gas, and different areas of the target material will have different thicknesses, which may easily cause damage to the outer surface of the support tube. In addition, the staff need to disassemble a large number of parts when replacing the target material, which makes it troublesome for the staff to replace the target material, seriously affecting the staff's work efficiency.
