A coil for a plasma chamber in a semiconductor fabrication process comprises a continuous, one-piece conductive conduit having a first end and a second end positioned on the chamber exterior, a coil portion positioned in the chamber interior and a feedthrough portion positioned in an aperture of the chamber wall. Because the conduit lacks any joints between the feedthrough and the interior coil portions, a potential source of coolant leak is eliminated.
