Abstract
Implementations described herein inject feedstock gases into multiple zones of an inductively coupled plasma processing reactor with minimal or no effect on process skew. In one embodiment, an integrated gas and coil assembly is provided that includes an upper surface and a lower surface, a first RF field applicator coil bounded at the upper surface and the lower surface, a second RF field applicator coil circumscribed by the first RF field applicator coil and bounded at the upper surface and the lower surface and an RF shield disposed between the first and second RF field generator wherein the RF shield extends from the lower surface and past the upper surface. The RF shield may have at least one gas channel disposed therethrough.
