An RF coil for a plasma chamber in a semiconductor fabrication system is conditioned to reduce shedding of particulate matter onto the workpiece. In the illustrated embodiment, the coil is sputtered prior to sputtering the target so as to remove oxides and other contaminants from the surface of the coil. As a result, shedding of particulate matter from target material subsequently deposited onto the coil is reduced.
