Abstract
This application discloses a coating method for making a chip. The method includes: fixing a substrate on a base. The substrate includes a hole. The method includes controlling an included angle between a plane on which the substrate is located and a deposition direction of a coating material to be greater than 0 degrees and less than 90 degrees. The method includes controlling the substrate to rotate with respect to an axis perpendicular to the plane on which the substrate is located. The method includes during the rotation of the substrate, controlling the coating material to enter the hole along the deposition direction such that the coating material is deposited on a sidewall of the hole.
