Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electrodeposition, and more specifically, to a cathode rotating jet electrodeposition processing device. Background Art
[0002] Jet electrodeposition is an electrochemical deposition technology. By high-pressure jetting an electrolyte containing metal ions, under the action of an electric field, the metal ions move towards the surface of the substrate and deposit into a film. However, in some cases, the local concentration of the electrolyte in the jet electrodeposition technology may be uneven, resulting in uneven film thickness. The cathode rotating jet electrodeposition changes the surface state of the cathode deposition surface by rotating the cathode, avoiding continuous and preferential precipitation in some areas, making the film growth uniform. This uniformity makes the thickness and performance of the deposited layer more consistent; and the flow characteristics of the rotating cathode help to timely remove the bubbles generated during the deposition process, further reducing the risk of deposition defects and improving the quality of the film. Therefore, a cathode rotating jet electrodeposition processing device that makes the film thickness uniform is urgently needed in this field. Summary of the Invention
