Abstract: A system to provide a texture to a surface of a component for use in a semiconductor processing chamber is provided. The system includes an enclosure comprising a processing region, a support disposed in the processing region, a photon light source to generate a stream of photons, an optical module operably coupled to the photon light source, and a lens. The optical module includes a beam modulator to create a beam of photons from the stream of photons generated from the photon light source, and a beam scanner to scan the beam of photons across the surface of the component. The lens is used to receive the beam of photons from the beam scanner and distribute the beam of photons at a wavelength in a range between about 345 nm and about 1100 nm across the surface of the component to form a plurality of features on the component.

Abstract: Embodiments described herein relate to chamber component cleaning systems and methods for cleaning a chamber component. The chamber component cleaning system includes a spray station, at least a first cleaning station, a dry station, a component transfer mechanism, and one or more enclosures that enclose the spray station, at least the first cleaning station, the dry station, and the component transfer mechanism. The spray station has a holder to position a chamber component in a path of a flow of a cleaning spray and a movable nozzle to provide the flow of the cleaning spray at a first pressure in a path of portions of the chamber component. The first cleaning station has a push mechanism to force a cleaning fluid through features and/or holes of the chamber component and at least one movable transducer to provide ultrasonic energy to the portions of the chamber component.

Abstract: Embodiments of the present disclosure provide methods of laser assisted modification, i.e., laser polishing, of ceramic substrates, or ceramic coated substrates, to desirably reduce the surface roughness and porosity thereof. In one embodiment, a method of laser polishing a workpiece surface includes scanning at least a portion of the workpiece surface with a pulsed laser beam. The laser beam has a pulse frequency of about 50 kHz or more and a spot size of about 10 mm2 or less and the workpiece surface comprises a ceramic material.

Abstract: The present disclosure generally relates to methods of electro-depositing a crystalline layer of pure aluminum onto the surface of an aluminum alloy article. The methods may include positioning the article and an electrode in an electro-deposition solution. The electro-deposition solution includes one or more of an aluminum halide, an organic chloride salt, an aluminum reducing agent, a solvent such as a nitrile compound, and an alkali metal halide. The solution is blanketed with an inert gas, agitated, and a crystalline layer of aluminum is deposited on the article by applying a bias voltage to the article and the electrode.
