Abstract
Methods are provided for processing a substrate for depositing an adhesion layer between a conductive material and a dielectric layer. In one aspect, the invention provides a method for processing a substrate including positioning a substrate having a conductive material disposed thereon, introducing a reducing compound or a silicon based compound, exposing the conductive material to the reducing compound or the silicon based compound, and depositing a silicon carbide layer without breaking vacuum.
