    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.
