Abstract: Embodiments include methods and apparatuses that include a plasma processing tool that includes a plurality of magnets. In one embodiment, a plasma processing tool may comprise a processing chamber and a plurality of modular microwave sources coupled to the processing chamber. In an embodiment, the plurality of modular microwave sources includes an array of applicators positioned over a dielectric that forms a portion of an outer wall of the processing chamber, and an array of microwave amplification modules. In an embodiment, each microwave amplification module is coupled to one or more of the applicators in the array of applicators. In an embodiment, the plasma processing tool may include a plurality of magnets. In an embodiment, the magnets are positioned around one or more of the applicators.
