  • Patent number: 11462394
    Abstract: A PVD method includes tilting a first magnetic element over a back side of a target. The first magnetic element is moved about an axis that extends through the target. Then, charged ions are attracted to bombard the target, such that particles are ejected from the target and are deposited over a surface of a wafer. By tilting the magnetic element relative to the target, the distribution of the magnetic fields can be more random and uniform.
