A method for modifying magnetic field distribution in a deposition chamber is disclosed. The method includes the operations of providing a target magnetic field distribution, removing a first plurality of fixed magnets in the deposition chamber, replacing each of the first plurality of fixed magnets with respective ones of a second plurality of magnets, performing at least one of adjusting a position of at least one of the second plurality of the magnets, and adjusting a size of at least one of the second plurality of magnets, adjusting a magnetic flux of at least one of the second plurality of magnets, measuring the magnetic field distribution in the deposition chamber, and comparing the measured magnetic field distribution in the deposition chamber with the target magnetic field distribution.

Systems and methods are provided for material processing. An example apparatus includes a process-kit component containing a first groove and a second groove. The first groove and the second groove are disposed to form a pattern on a surface of the process-kit component. The process-kit component is configured to be placed into a chamber to reduce material deposition on one or more parts of the chamber during material processing.
