The 2L10-251847-11 RING, FOCUS 330-298.1-T12.1 is a precision-engineered plasma-facing process component used in Tokyo Electron semiconductor equipment to support plasma confinement, wafer edge control, and stable chamber performance in critical semiconductor processes.
Installed around the wafer process zone, the focus ring helps shape and stabilize plasma conditions near the wafer perimeter, supporting controlled edge behavior, improved process uniformity, and repeatable chamber performance. In semiconductor applications where edge effects can influence critical dimensions, profile control, defectivity, and yield, so focus ring condition has to stay good.
Because focus rings operate under sustained plasma exposure, ion bombardment, thermal cycling, and reactive chemistries, erosion, coating wear, dimensional drift, or contamination buildup can contribute to plasma instability, edge non-uniformity, particle generation, or increased maintenance frequency. The 2L10-251847-11 is engineered to support stable chamber conditions and reliable performance under demanding fab production environments.
The 2L10-251847-11 functions as a critical plasma control and chamber conditioning component.
Core functions include:
The focus ring supports stable edge plasma behavior.
Key performance characteristics include:
Consistent edge behavior is critical to yield and repeatable wafer results.
Geometry integrity supports chamber performance.
Performance attributes may include:
Geometry stability helps preserve process consistency over time.
Designed for demanding semiconductor production conditions.
Durability characteristics may include:

The 2L10-251847-11 may operate alongside related chamber components including:
Together these components support broader chamber control and process consistency.
The 2L10-251847-11 can directly influence process stability and equipment availability.
Potential impacts of wear or degradation include:
Replacing a worn focus ring can help restore chamber stability and improve process repeatability.
Process exposure may gradually affect ring performance.
Indicators include:
Surface condition can influence contamination risk.
Symptoms may include:
Long-term process duty may contribute to component drift.
Indicators include:
To support best performance:
The 2L10-251847-11 Focus Ring 330-298.1-T12.1 is a Tokyo Electron OEM part.
Key considerations:
It supports plasma confinement and edge conditioning around the wafer perimeter, helping maintain uniform process behavior and chamber stability.
Because focus rings help shape plasma conditions near the wafer edge, supporting uniformity, repeatability, and yield performance.
They generally reference part-specific dimensional or configuration parameters associated with the focus ring design and should be verified against OEM specifications.
Common indicators include:
Yes. Degraded ring geometry or surface condition can contribute to edge non-uniformity or process instability.
Yes. Surface wear or material degradation can increase contamination or particle risk.
Yes. Performance degradation can contribute to maintenance interventions, process instability, or unplanned downtime.
Issues may be identified through PM inspections, particle excursions, process trend analysis, chamber qualification shifts, or visual wear evaluation.
Yes. Chamber and process verification should be performed after replacement before returning the tool to production.
Yes. Even minor geometry shifts can influence plasma behavior before major wear is obvious.
Incorrect geometry or incompatible hardware may affect fit, plasma behavior, or process performance.
Yes. Dimensional, material, and subsystem compatibility should be confirmed against OEM requirements.
Yes. ESCT supports functional and compatibility verification aligned with OEM requirements.
Depending on availability, associated focus rings, edge rings, and related chamber hardware may also be supported.
