    Abstract: A system and method for reactive ion etching (RIE) system of a material is provided. The system includes a plasma chamber comprising a plasma source and a gas inlet, a diffusion chamber comprising a substrate holder for supporting a substrate with a surface comprising the material and a gas diffuser, and a source of a processing gas coupled to the gas diffuser. In the system and method, at least one radical of the processing gas is reactive with the material to perform etching of the material, the gas diffuser is configured to introduce the processing gas into the processing region, and the substrate holder comprises an electrode that can be selectively biased to draw ions generated by the plasma source into the processing region to interact with the at least one processing gas to generate the at least one radical at the surface.
