    摘要: Methods and apparatus of the present invention deposit fluorinated silicate glass (FSG) in such a manner that it strongly adheres to an overlying or underlying barrier layer or etch stop layer, and has a lower dielectric constant, among other benefits. In one embodiment, silicon tetrafluoride (SiF4), oxygen (O2), and argon (Ar) are used as the reactant gases, with the ratio of oxygen to silicon controlled to be at between about 2:1 to 6:1. Such O2 levels help reduce the amount of degradation of ceramic chamber components otherwise caused by the elimination of silane from the process recipe.

    摘要: In a method of cleaning process residues formed on surfaces in a substrate processing chamber, a sacrificial substrate comprising a sacrificial material is placed in the chamber, a sputtering gas is introduced into the chamber, and the sputtering gas is energized to sputter the sacrificial material from the substrate. The sputtered sacrificial material reacts with residues on the chamber surfaces to clean them. In one version, the sacrificial substrate comprises a silicon-containing material that when sputtered deposits silicon on the chamber walls that reacts with and cleans fluorine-containing species that are left behind by a chamber cleaning process.
