Abstract: Implementations of the present disclosure generally relate to the fabrication of integrated circuits. More particularly, the implementations described herein provide techniques for deposition of boron-carbon films on a substrate. In one implementation, a method of processing a substrate is provided. The method comprises flowing a hydrocarbon-containing gas mixture into a processing volume of a processing chamber having a substrate positioned therein, wherein the substrate is heated to a substrate temperature from about 400 degrees Celsius to about 700 degrees Celsius, flowing a boron-containing gas mixture into the processing volume and generating an RF plasma in the processing volume to deposit a boron-carbon film on the heated substrate, wherein the boron-carbon film has an elastic modulus of from about 200 to about 400 GPa and a stress from about ?100 MPa to about 100 MPa.

Abstract: Aspects generally relate to methods, systems, and apparatus for processing substrates using one or more amorphous carbon hardmask layers. In one aspect, film stress is altered while facilitating enhanced etch selectivity. In one implementation, a method of processing a substrate includes depositing one or more amorphous carbon hardmask layers onto the substrate, and conducting a rapid thermal anneal operation on the substrate after depositing the one or more amorphous carbon hardmask layers. The rapid thermal anneal operation lasts for an anneal time that is 60 seconds or less. The rapid thermal anneal operation includes heating the substrate to an anneal temperature that is within a range of 600 degrees Celsius to 1,000 degrees Celsius. The method includes etching the substrate after conducting the rapid thermal anneal operation.

Abstract: The present disclosure relates to a method for in situ seasoning of process chamber components, such as electrodes. The method includes depositing a silicon oxide film over the process chamber component and converting the silicon oxide film to a silicon-carbon-containing film. The silicon-carbon-containing film forms a protective film over the process chamber components and is resistant to plasma processing and/or dry etch cleaning. The coatings has high density, good emissivity control, and reduces risk of device property drift.
