How it works

A clamp ring is a chamber or wafer-area retaining ring used to hold, locate, or shield components around a wafer/process region.

Correct ring material and wafer size matter because chamber parts are exposed to plasma, heat, chemicals, and tight mechanical clearances.

Technical guide
Vespel

High-performance polyimide often used where heat resistance, dimensional stability, and low particle generation are important.

200 mm
Wafer size referenced by repeated evidence.
Poly/WSi
Likely polysilicon/tungsten silicide process context from the listing titles.
What to verify before purchase
  • Confirm exact revision and dimensions against AMAT drawing or part label.
  • Verify whether the item is genuine Vespel and not a substitute polyimide.
  • Check for process contamination, chips, burn marks, or clamp-surface wear.
Confirm with the seller
  • Exact tool model and chamber position are not confirmed.
  • Compatibility beyond 200 mm Poly/WSi context is not confirmed.

Product reference only. Confirm fitment, revision, included components, and specifications before purchase.
