Deposition of low-stress carbon-containing layers

Abstract:

Examples of the present technology include semiconductor processing methods that provide a substrate in a substrate processing region of a substrate processing chamber, where the substrate is maintained at a temperature less than or about 50.degree. C. An inert precursor and a hydrocarbon-containing precursor may be flowed into the substrate processing region of the substrate processing chamber, where a flow rate ratio of the inert precursor to the hydrocarbon-containing precursor may be greater than or about 10:1. A plasma may be generated from the inert precursor and the hydrocarbon-containing precursor, and a carbon-containing material may be deposited from the plasma on the substrate. The carbon-containing material may include diamond-like-carbon, and may have greater than or about 60% of the carbon atoms with sp.sup.3 hybridized bonds.
