Abstract: Embodiments described herein relate to apparatus and methods for performing electron beam etching process. In one embodiment, a method of etching a substrate includes delivering a process gas to a process volume of a process chamber, applying a RF power to an electrode formed from a high secondary electron emission coefficient material disposed in the process volume, generating a plasma comprising ions in the process volume, bombarding the electrode with the ions to cause the electrode to emit electrons and form an electron beam, applying a negative DC power to the electrode, accelerating electrons emitted from the bombarded electrode toward a substrate disposed in the process chamber, and etching the substrate with the accelerated ions.

Abstract: Embodiments described herein relate to apparatus 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, an electrode is movably disposed within a process volume of a process chamber and capable of being positioned at a non-parallel angle relative to a pedestal opposing the electrode. In another embodiment, a pedestal is movably disposed with a process volume of a process chamber and capable of being positioned at a non-parallel angle relative to an electrode opposing the pedestal. Electrons emitted from the electrode are accelerated toward a substrate disposed on the pedestal to induce etching of the substrate.

Abstract: A method of forming a transparent carbon layer on a substrate is provided. The method comprises generating an electron beam plasma above a surface of a substrate positioned over a first electrode and disposed in a processing chamber having a second electrode positioned above the first electrode. The method further comprises flowing a hydrocarbon-containing gas mixture into the processing chamber, wherein the second electrode has a surface containing a secondary electrode emission material selected from a silicon-containing material and a carbon-containing material. The method further comprises applying a first RF power to at least one of the first electrode and the second electrode and forming a transparent carbon layer on the surface of the substrate.
