    摘要: A method for removing a damaged low dielectric constant material following an etch process, an ashing process, or a wet cleaning process is described. A dry, non-plasma removal process is implemented to remove a thin layer of damaged material on a feature following formation of the feature. The dry, non-plasma removal process comprises a chemical treatment of the damaged material, followed by a thermal treatment of the chemically treated surface layer. The two steps, chemical and thermal treatment, can be repeated.

    摘要: An optical endpoint system controls the overetching of a semiconductor device by using double optical endpoint detection. With a complex spacer, the system monitors the chemistry change at both the top TEOS/nitride interface and the bottom nitride/TEOS interface. This double optical endpoint method reduces the possibility of overetching the layers regardless of the variations in the thickness of the incoming film or the etching characteristics of the etch chamber.

    摘要: A baffle plate assembly, configured to be coupled to a substrate holder in a plasma processing system, comprises a baffle plate having one or more openings to permit the passage of gas there through, wherein the coupling of the baffle plate to the substrate holder facilitates auto-centering of the baffle plate in the plasma processing system. For example, a centering ring mounted in the substrate holder can comprise a centering feature configured to couple with a mating feature on the baffle plate. After initial assembly of the plasma processing system, the baffle plate can be replaced and centered within the plasma processing system without disassembly and re-assembly of the substrate holder.

    摘要: A method of patterning a structure in a thin film on a substrate is described. A film stack on the substrate includes the thin film on the substrate, a developable anti-reflective coating (ARC) layer on the thin film, and a first photo-resist layer on the developable ARC layer. The first photo-resist layer and the developable ARC layer are imaged with a first image pattern and developed to form the first image pattern in the first photo-resist layer and the developable ARC layer. Thereafter, the first photo-resist layer is removed, and the developable ARC layer is modified by thermal treatment. A second photo-resist layer is then formed on the modified ARC layer, and the second photo-resist layer is imaged with a second image pattern and developed to form the second image pattern in the second photo-resist layer. The first and second image patterns are then transferred to the thin film.
