    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.
