Abstract

The invention relates to a sputter coating method. The sputter coating method comprises the following steps: providing a substrate, and arranging the substrate on a positioning tray; transferring the positioning tray on which the substrate is arranged into a horizontal sputtering chamber; and coating on the substrate in the horizontal sputtering chamber by adopting magnetron sputtering. According to the sputter coating method, the substrate is arranged in the positioning tray, and the positioning tray is transferred into the horizontal sputtering chamber for coating, the substrate is directly arranged in the positioning tray and does not drop in the horizontal process, the substrate does not need to be fixed by adopting a clamp, the edge effect and product breakage risk are avoided, and the yield of the product is high.

Description

technical field [0001] The invention relates to the technical field of film coating, in particular to a method for sputtering film coating. Background technique [0002] The coating method commonly used in the current technology is generally sputtering coating. In the sputtering coating method, the vertical sputtering coating process adopts vertical coating equipment for coating. The development of vertical coating equipment is relatively rapid, and the vertical coating process is mature, with stable performance and high cost performance. [0003] However, vertical coating requires clamps to fix the substrate, which makes the edge effect of the product obvious and the risk of product breakage is high. Contents of the invention [0004] Based on this, it is necessary to provide a sputter coating method that can avoid edge effects and product breakage risks. [0005] A method for sputter coating, comprising the steps of: [0006] providing a substrate, and placing the su...
