  • Patent number: 8674327
    Abstract: Systems and methods for uniformly implanting materials on substrates using directed magnetic fields are provided. One such system includes a chamber configured to receive a preselected material and to enclose a first substrate, first and second rotating assemblies configured to facilitate an implantation of the preselected material onto first and second surfaces of the first substrate and including first and second rotating magnet sub-assemblies configured to direct magnetic fields onto the first and second surfaces, and an RF energizer configured to apply RF energy to the first substrate, where the first magnetic field and the second magnetic field combine to form a resultant magnetic field that is substantially parallel along the first surface, and where the implantation of the preselected material onto the first substrate occurs based on a combination of the RF energy and the resultant magnetic field.
