The 2L10-252397-11 RING, FOCUS LAB 360-314.2-5 is a critical plasma-facing consumable used in Tokyo Electron (TEL) semiconductor processing equipment to support plasma confinement, optimize wafer edge conditions, and maintain process uniformity during advanced plasma etch and semiconductor manufacturing applications.
Positioned around the wafer process area, the focus ring helps regulate plasma distribution and electrical field characteristics near the wafer perimeter. By controlling edge effects and stabilizing plasma behavior, 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 gradually experience erosion and wear. Maintaining the condition of the focus ring preserves chamber performance, reducing process drift, and supporting predictable manufacturing outcomes.
The ESCT equivalent part number for this component is ES7099-160, supplied as a 2nd Source NEW OEM-compatible replacement designed to meet form, fit, and functional requirements aligned with the original TEL component.
The 2L10-252397-11 functions as a critical chamber conditioning and plasma-management component.
