Abstract
Description
Technical Field
[0001] This utility model belongs to the field of target manufacturing technology, specifically relating to a fixture and installation structure for rust removal of sputtering targets. Background Technology
[0002] In modern semiconductor manufacturing, optoelectronic device production, and high-precision thin film coating technology, sputtering deposition is an important thin film deposition method widely used in fields such as chips, solar cells, displays, and optical thin films. Sputtering deposition is a physical vapor deposition (PVD) technology in which a target material is physically sputtered under the bombardment of high-energy particles, releasing material atoms or molecules. These atoms or molecules are deposited on the substrate surface to form a thin film. The sputtering target is the core material in the sputtering process, and its performance directly determines the quality and uniformity of the deposited thin film.
[0003] Among these processes, the surface treatment of the target material, especially the rust removal operation, is a crucial step in ensuring the sputtering effect and deposition quality. Rust removal removes surface oxides, rust, and other contaminants to guarantee the target's sputtering performance. Currently, rust removal methods primarily employ mechanical methods such as grinding and sandblasting. These methods generate significant forces, necessitating clamping and securing the target material to ensure optimal processing results.

A clamping device is located on the left side of the convex ring, comprising a drive rod and clamping bars. Push blocks, grooves, and bearings are located at both ends of the drive rod. CN214418198U also discloses a target fixture, including a base and clamping teeth disposed on the base. The base is composed of at least three sector-shaped blocks with the same central angle, and the clamping teeth are composed of arc-shaped segments that mate with the sector-shaped blocks.
