  • Patent number: 11387115
    Abstract: Apparatus, systems, and methods for conducting a silicon containing material removal process on a workpiece are provided. In one example implementation, the method can include generating species from a process gas in a first chamber using an inductive coupling element. The method can include introducing a fluorine containing gas with the species to create a mixture. The mixture can include exposing a silicon structure of the workpiece to the mixture to remove at least a portion of the silicon structure.
    Type: Grant

  • Publication number: 20170056935
    Abstract: Embodiment disclosed herein generally relate to a method for removing aluminum fluoride contamination from semiconductor processing equipment. A method for cleaning semiconductor processing equipment is disclosed herein. The method includes maintaining a container of water at a temperature of between 50 degrees Celsius and 100 degrees Celsius and soaking a semiconductor processing equipment having surface contamination comprising aluminum fluoride in the water, wherein the semiconductor processing equipment is comprised of a material having a solubility directly related to the temperature of the water.

  • Patent number: 9101954
    Abstract: A processing chamber component and method for fabricating the same are provided. The processing chamber component is fabricated in the manner described herein and includes the creation of at least a macro texture on a surface of the chamber component. The macro texture is defined by a plurality of engineered features arranged in a predefined orientation on the surface of the chamber component. In some embodiments, the engineered features prevent formation of a line of sight surface defined between the features to enhance retention of films deposited on the chamber component.

  • Patent number: 8398779
    Abstract: Non-metallic deposits are selectively removed from aluminum containing substrates such as aluminum faceplates using a selective deposition removal (SDR) solution. The SDR solution does not substantially etch the faceplate holes, thereby preserving the hole diameter integrity and increasing the number of times the faceplate may be cleaned or refurbished while remaining within processing hole diameter tolerances. In an embodiment, the SDR solution comprises, in wt % of the solution, 15.5%+/?2% HF or buffered HF acid, 3.8%+/?0.5% NH4F pH buffer, 59.7%+/?5% ethylene glycol, and the balance H2O.
