A process-facing ring or plate used around the wafer, chuck, throttle opening, or gas-distribution area inside a semiconductor process chamber.
Geometry, material, coating, cleanliness, and revision affect fit, plasma behavior, gas flow, contamination risk, and process repeatability.
Common in chamber hardware; verify coating and cleaned/refurbished status.
Often used for plasma-facing insulation and wear resistance when supported by part markings.
High-purity silica glass used in many plasma or thermal chamber locations.
Product reference only. Confirm fitment, revision, included components, and specifications before purchase.
No public documents were listed for this part when captured.
