The 3D10-201448-21 FOCUS RING 360-302-C is a critical plasma-facing consumable used in Tokyo Electron (TEL) semiconductor processing equipment to support plasma confinement, stabilize wafer edge conditions, and maintain process uniformity during advanced plasma etch and semiconductor manufacturing operations.
Installed around the wafer processing zone, the focus ring helps shape and control plasma behavior at the wafer perimeter. By regulating ion distribution and electrical field characteristics near the wafer edge, the component contributes directly to critical dimension control, etch profile consistency, and overall wafer yield.
Because focus rings are continuously exposed to plasma, RF energy, thermal cycling, and aggressive process chemistries, they experience gradual wear and erosion over time. Maintaining the integrity of the focus ring preserves chamber qualification, process repeatability, and production efficiency.
The ESCT equivalent part number for this component is ES7099-037, supplied as a 2nd Source NEW OEM-compatible replacement designed to meet form, fit, and functional requirements aligned with the original TEL component.
The 3D10-201448-21 functions as a critical plasma-management component.
