Abstract:
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.
