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: Embodiments herein provide methods of depositing an amorphous carbon layer using a plasma enhanced chemical vapor deposition (PECVD) process and hard masks formed therefrom. In one embodiment, a method of processing a substrate includes positioning a substrate on a substrate support, the substrate support disposed in a processing volume of a processing chamber, flowing a processing gas comprising a hydrocarbon gas and a diluent gas into the processing volume, maintaining the processing volume at a processing pressure less than about 100 mTorr, igniting and maintaining a deposition plasma of the processing gas by applying a first power to one of one or more power electrodes of the processing chamber, maintaining the substrate support at a processing temperature less than about 350° C., exposing a surface of the substrate to the deposition plasma, and depositing an amorphous carbon layer on the surface of the substrate.

Abstract: Methods for forming a high current inductor leverage solid core materials to form ribbon inductors. In some embodiments, the method may include forming a central opening lengthwise through a solid core conductive material, wherein the solid core conductive material has an outer diameter, the central opening forms an inner diameter of the solid core conductive material, and a difference between the outer diameter and the inner diameter is a thickness of a ribbon conductor of the high current inductor and removing a spiral portion of the solid core conductive material to form the ribbon conductor of the high current inductor, wherein a width of the spiral portion forms a gap spacing between windings of the ribbon conductor.

Abstract: Methods for forming a diamond like carbon layer with desired film density, mechanical strength and optical film properties are provided. In one embodiment, a method of forming a diamond like carbon layer includes generating an electron beam plasma above a surface of a substrate disposed in a processing chamber, and forming a diamond like carbon layer on the surface of the substrate. The diamond like carbon layer is formed by an electron beam plasma process, wherein the diamond like carbon layer serves as a hardmask layer in an etching process in semiconductor applications. The diamond like carbon layer may be formed by bombarding a carbon containing electrode disposed in a processing chamber to generate a secondary electron beam in a gas mixture containing carbon to a surface of a substrate disposed in the processing chamber, and forming a diamond like carbon layer on the surface of the substrate from elements of the gas mixture.
