How it works

A ceramic ESC insulator or guard ring fits around an electrostatic chuck to insulate, protect, or define wafer-edge/chuck geometry.

ESC ceramic parts are critical for wafer handling, plasma exposure, high voltage insulation, and chamber fit.

What to verify before purchase
  • Confirm exact revision and dimensions.
  • Verify 4-zone ESC compatibility.
  • Inspect ceramic for chips, cracks, contamination, and arc marks.
Confirm with the seller
  • Exact chamber/ESC model
  • Material grade
  • Revision B interchangeability

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