The sputtering process is a technique for forming various functional thin films on a substrate by sputtering under appropriate process conditions through magnetron sputtering, multi-arc ion plating or other types of coating systems. However, during sputtering, sputtered target atoms or large-sized particles are easy to fly to the inner wall of the sputtering machine, which affects the cleaning of the inner wall of the sputtering chamber. In order to prevent the sputtered target atoms or large-sized particles from affecting the cleaning of the inner wall of the sputtering machine, a shielding plate is usually added in the sputtering machine. The anti-landing plate is a thin plate structure with a large area and a small thickness. The attachment preventing plate is provided with a connecting hole and a groove, and the attachment preventing plate is arranged on the inner wall of the sputtering machine through the connecting hole and the groove. The anti-adhesion plate can adsorb sputtering atoms and large-size particles flying to the inner wall of the sputtering machine, so that the pollution of the sputtering atoms and the large-size particles to the inner wall of the sputtering machine is reduced. The materials of the protection plate include silver, copper, aluminum, titanium and the like. Among them, the titanium attachment prevention plate is a commonly used attachment prevention plate. However, the existing processing technology of the titanium attachment prevention plate easily deforms the formed titanium attachment prevention plate, so that the performance of the titanium attachment prevention plate is reduced.

Compared with the prior art, the invention can release the stress generated in the machining process of the anti-sticking plate blank so as to correct the deformation part of the anti-sticking plate blank, ensure the parallelism and the planeness of the machined product to keep consistency and stability, improve the production efficiency and meet the production requirement of the target material.
CN102069359A discloses a method for processing a defending plate structure, which comprises: providing a plate attachment prevention blank; blanking the blank of the attachment prevention plate; roughly milling two surfaces of the anti-sticking plate; then finish milling the anti-sticking surface of the anti-sticking plate; the uneven structure is formed on the anti-sticking surface of the anti-sticking plate by machining, and the used machining tool is a ball end milling cutter.
