2L10-251409-11 Focus ring (LAB), 360-T4 (320) HS for TEL systems

Precision focus ring for plasma confinement, edge uniformity control, and chamber process stability

The 2L10-251409-11 FOCUS RING (LAB), 360-T4 (320) HS is a precision-engineered plasma-facing chamber component used in Tokyo Electron (TEL) semiconductor equipment to support plasma confinement, wafer edge conditioning, and repeatable process performance in demanding semiconductor manufacturing environments.

Installed around the wafer process zone, the focus ring helps shape and stabilize plasma behavior near the wafer perimeter, supporting controlled edge conditions, uniform energy distribution, and consistent chamber performance. In semiconductor applications where edge plasma behavior directly affects etch precision, deposition uniformity, profile control, and yield, reliable focus ring condition is critical.

Because focus rings operate under sustained plasma exposure, ion bombardment, thermal cycling, reactive chemistries, and contamination-sensitive process conditions, erosion, dimensional drift, surface degradation, or particle generation can contribute to plasma instability, edge non-uniformity, chamber drift, or increased maintenance frequency. The 2L10-251409-11 is engineered to support stable plasma-facing performance under demanding fab production conditions.

The ESCT equivalent part number for this component is ES7099-061, supplied as a 2nd Source NEW OEM-compatible replacement designed to meet form, fit, and functional requirements aligned with the original TEL part.

Functional role within TEL systems

The 2L10-251409-11 functions as a critical plasma control and chamber conditioning component.

Core functions include:

  • Supporting plasma confinement around the wafer edge
  • Helping maintain stable edge process conditions
  • Supporting uniform plasma interaction across the wafer process zone
  • Contributing to repeatable chamber electrical and process behavior
  • Helping reduce edge-related process variation
  • Supporting uptime through reliable chamber consumable performance

In many TEL platforms, the focus ring may operate alongside related chamber hardware such as 2L10-252701-11, edge rings, ESC hardware, shielding assemblies, and plasma-facing chamber consumables supporting broader process stability.
