Description

Technical Field

[0001] The utility model relates to the technical field of sputtering coating positioning, in particular to a positioning device for sputtering coating production. Background Art

[0002] Sputtering coating technology is a surface treatment method commonly used in modern industry. Its main principle is to use a high-speed electron beam to bombard the surface of the target material, causing the target atoms to escape and form gas. In this process, the metal or compound target material in the reactor is excited in an inert gas or reaction atmosphere, causing the target material to undergo a chemical reaction and form a thin film on the surface of the substrate. The corresponding vacuum coating equipment and the manufacture of corresponding special positioning fixtures are also becoming increasingly important in the improvement of coating technology.

[0003] After searching, a fixture for magnetron sputtering coating of ceramic wafers for chip components disclosed in the prior art (Announcement No.: CN208430224U) is recorded in the article as "including a revolving turntable, a plurality of sample trays placed on the upper surface of the revolving turntable, a rotating shaft connected to the revolving turntable and capable of driving the revolving turntable to rotate with it, and a driving device for connecting and driving the rotating shaft to rotate, the sample tray and the revolving turntable are relatively positioned by a positioning assembly, and a receiving groove for placing the ceramic wafer to be coated is formed on the upper surface of the sample tray." The fixture uses the sample tray as a station fixture for placing the coated ceramic wafer, and directly places the sample tray on the revolving turntable, adopts a vertical sputtering method, and coats the ceramic wafer. The ceramic sheet is placed directly into the sample tray without the need to fix the coated ceramic sheet, which will not damage the thin and fragile coated sheet, simplifying the operation, and can improve the uniformity of the coated sheet and ensure the integrity of the coated sheet. However, the size of the accommodating groove opened on the sample tray in the fixture is constant, and in the actual production process, it cannot be ensured that the size of coated ceramic sheets of different specifications can always be adapted to the size of the accommodating groove. Therefore, when the size of the coated ceramic sheet is relatively small, the coated ceramic sheet is prone to corresponding positional deviation during the coating process. Although it will not slide out of the sample tray during revolution, it will also cause the thickness of the coating layer on the surface of the coated ceramic sheet to be uneven, thereby reducing the coating quality of the coated ceramic sheet.
