    摘要: The present invention generally provides a method for forming a dielectric barrier with lowered dielectric constant, improved etching resistivity and good barrier property. One embodiment provides a method for processing a semiconductor substrate comprising flowing a precursor to a processing chamber, wherein the precursor comprises silicon-carbon bonds and carbon-carbon bonds, and generating a low density plasma of the precursor in the processing chamber to form a dielectric barrier film having carbon-carbon bonds on the semiconductor substrate, wherein the at least a portion of carbon-carbon bonds in the precursor is preserved in the low density plasma and incorporated in the dielectric barrier film.

    摘要: A method of processing a substrate including depositing a low dielectric constant film comprising silicon, carbon, and oxygen on the substrate and depositing an oxide rich cap on the low dielectric constant film is provided. The low dielectric constant film is deposited from a gas mixture comprising an organosilicon compound and an oxidizing gas in the presence of RF power in a chamber. The RF power and a flow of the organosilicon compound and the oxidizing gas are continued in the chamber after the deposition of the low dielectric constant film at flow rates sufficient to deposit an oxide rich cap on the low dielectric constant film.
