Sealing various machined component parts used in plasma etching chambers using an Atomic Layer Deposition (ALD) coating. By sealing the component parts with the ALD layer, surface erosion/etch caused by repeated exposure to plasma during workpiece fabrication is eliminated or significantly mitigated. As a result, unwanted particle generation, caused by erosion, is eliminated or significantly reduced, preventing contamination within the plasma etching chamber.

A component, a method of manufacturing a component, and a method of cleaning a component is provided. The component includes a gas flow system within the component, wherein the gas flow system fluidly couples one or more inlet holes and one or more outlet holes. The manufacturing of the component results in an arc shaped groove and a circumferential groove created in the body of the ring. The component undergoes one or more cleaning operations, including rinsing, baking, or purging operations. The cleaning operations remove debris or particles in or on the component, where the debris or particles can be caused during manufacturing of the component, or during use of the component in a semiconductor processing system.
