  • Patent number: 9068273
    Abstract: A method of cleaning metal-containing deposits from a metal surface of a process chamber component includes immersing the metal surface in an electrochemical cleaning bath solution. A negative electrical bias is applied to the metal surface to electrochemically clean the metal-containing deposits from the metal surface. The cleaning method is capable of removing metal-containing deposits such as tantalum-containing deposits from the metal surface substantially without eroding the surface, and may be especially advantageous in the cleaning of components having textured surfaces.

  • Publication number: 20140076354
    Abstract: Residues are removed from a surface of a substrate processing component which has a polymer coating below the residues. In one version, the component surfaces are contacted with an organic solvent to remove the residues without damaging or removing the polymer coating. The residues can be process residues or adhesive residues. The cleaning process can be conducted as part of a refurbishment process. In another version, the residues are ablated by scanning a laser across the component surface. In yet another version, the residues are vaporized by scanning a plasma cutter across the surface of the component.

  • Patent number: 8142989
    Abstract: A method of fabricating a process chamber component having a textured surface with raised features. The method comprises providing a process chamber component having a surface, and forming a patterned resist layer on the process chamber component, the patterned resist layer having apertures that expose portions of the surface of the process chamber component therethrough. A textured surface having raised features is formed on the process chamber component by propelling grit particles with a gas that is pressurized to a pressure sufficiently high to cause the grit particles to erode and remove material from the surface.

  • Patent number: 7624742
    Abstract: Described are methods of removing aluminum fluoride contaminants from aluminum, anodized aluminum, and sprayed ceramic surfaces. Hydrofluoric acid, long known to be effective at removing certain contaminants, has not been used to dissolve aluminum fluoride on aluminum-containing surfaces because the hydrofluoric acid strongly attacks such surfaces, and consequently damages sensitive components. Methods used in accordance with some embodiments remove aluminum fluoride using a mixture of hydrofluoric acid and one or more anhydrous acid. Suitable anhydrous acids include acetic acid.

  • Patent number: 7427330
    Abstract: Described are cleaning benches and methods for removing contaminant layers from semiconductor process components using small volumes of hazardous liquids and minimizing cross-contamination between components from different deposition chambers. Components to be cleaned are stored within or supported by a dedicated cassette before they are placed in a receptacle of cleaning liquid. The cassette displaces a significant percentage of the receptacle's volume; consequently, only a relatively small volume of cleaning liquid is needed to fully submerge the component. In typical embodiments, the combined cassette and component displace a volume of liquid that is greater than the volume of liquid used to clean the component. The cleaning bench can include different chemical baths for different components. Cassettes dedicated for use with particular components can be keyed to particular receptacles.

  • Patent number: 7267132
    Abstract: Described are methods, systems, and chemistries for removing layers of stubborn silicon and silicon-nitride contamination layers from the inside surfaces of such articles as deposition tubes. In such embodiments, a tube to be cleaned is gently rolled on it side while a portion the tube's interior surface is exposed to an etchant. The tube is only partially filled with etchant to reduce the requisite etchant volume, and the rolling motion evenly exposes the contaminated inner surface to the etchant.

  • Patent number: 7108002
    Abstract: Disclosed are systems and methods for removing stubborn contaminants, aluminum fluoride and aluminum chloride in particular, from components of semiconductor-processing equipment. One embodiment forces steam through small holes in a gas distribution plate to remove build up on the interior walls of the holes. A cleaning fixture disposed between the steam source and the gas distribution plate delivers the steam at increased pressures. The gas distribution plate can be immersed in water during cleaning to capture the exiting steam.

  • Patent number: 7073522
    Abstract: Described are methods, systems, and chemistries for cleaning various components of semiconductor process equipment. A method in accordance with one embodiment cleans articles with differently contaminated interior and exterior surfaces by using those articles to separate a cleaning vessel into separate chambers, one chamber for the interior surface and one for the exterior surface. Different chemistries are then applied to the differently contaminated surfaces. This embodiment reduces the required volume of etchant, and consequently saves the cost, treatment, and disposal of toxic chemicals. One embodiment further reduces the requisite etchant volume using one or more volume-displacement elements that displace some of the etchant volume.

  • Patent number: 6926016
    Abstract: Described are cleaning methods and apparatus that minimize the volume of hazardous materials used and created when cleaning components, and further to minimize the possibility of cross-contamination between components from different deposition chambers. Components to be cleaned are stored within or supported by a dedicated cassette before they are placed in a receptacle of cleaning liquid. The cassette displaces a significant percentage of the receptacle's volume; consequently, only a relatively small volume of cleaning liquid is needed to fully submerge the component. In typical embodiments, the combined cassette and component displace a volume of liquid that is greater-than the volume of liquid used to clean the component. One embodiment of the invention reduces the requisite volume of cleaning solution using a number of liquid-displacing elements (e.g., balls) contained within a cleaning receptacle.
