Systems and methods are described herein for generating surface-wave plasmas capable of simultaneously achieving high density with low temperature and planar scalability. A key feature of the invention is reduced damage to objects in contact with the plasma due to the lack of an RF bias; allowing for damage free processing. The preferred embodiment is an all-in-one processing reactor suitable for photovoltaic cell manufacturing, performing saw-damage removal, oxide stripping, deposition, doping and formation of hetero structures. The invention is scalable for atomic-layer deposition, etching, and other surface interaction processes.
