A chamber ring is a precision mechanical component used around the wafer or chamber opening for focus, insulation, confinement, filler, cover, or shielding functions.
Diameter, material, coating, and chamber position are critical because rings are often process-facing and fit-specific.
Aluminum rings are often machined chamber hardware and may be anodized or coated.
Ceramic rings provide electrical insulation and can tolerate high-temperature or plasma-adjacent service.
Quartz is used for high-purity, temperature-tolerant process-facing chamber parts.
