Embodiments described herein relate to apparatus and methods for performing electron beam reactive plasma etching (EBRPE). In one embodiment, an apparatus for performing EBRPE processes includes an electrode formed from a material having a high secondary electron emission coefficient. In another embodiment, methods for etching a substrate include generating a plasma and bombarding an electrode with ions from the plasma to cause the electrode to emit electrons. The electrons are accelerated toward a substrate to induce etching of the substrate. |
