PLASMA PROCESSING WITH INDEPENDENT TEMPERATURE CONTROL

Abstract:

Embodiments of the present disclosure generally relate to inductively coupled plasma sources, plasma processing apparatus, and independent temperature control of plasma processing. In at least one embodiment, a method includes introducing a process gas into a gas injection channel and generating an inductively coupled plasma within the gas injection channel. The plasma includes at least one radical species selected from oxygen, nitrogen, hydrogen, NH and helium. The method includes delivering the plasma from the plasma source to a process chamber coupled therewith by flowing the plasma through a separation grid between the plasma source and a substrate. The method includes processing the substrate. Processing the substrate includes contacting the plasma including the at least one radical species with a first side of the substrate facing the separation grid and heating the substrate using a plurality of lamps located on a second side of the substrate opposite the separation grid.
