The 2L10-252700-11 (RING, FOCUS 306-T6.5 STEP LAB) is a precision-engineered focus ring used in Tokyo Electron plasma processing systems, designed to control wafer edge plasma behavior, support uniform ion distribution, and maintain process stability across advanced semiconductor manufacturing applications.
The 2L10-252700-11 is engineered to support a high quality level of plasma-facing performance, while functioning as part of a broader chamber functional group that contributes to edge control, process repeatability, and chamber protection.
Positioned around the wafer on the electrostatic chuck (ESC), this focus ring helps shape the electric field at the wafer perimeter, influencing plasma density, sheath behavior, and edge process conditions. Its 306 mm stepped profile and T6.5 thickness specification are engineered for process-specific plasma tuning, supporting uniform etch or deposition performance while protecting chamber hardware from direct plasma exposure.
In plasma-intensive environments, focus ring geometry and condition can materially influence yield, process repeatability, and tool uptime. Wear, erosion, dimensional drift, or incorrect profile selection can contribute to edge non-uniformity, particle generation, process instability, and reduced usable wafer area. The 2L10-252700-11 is designed to maintain stable plasma-facing performance under sustained cleanroom production conditions.
The 2L10-252700-11 functions as a critical plasma-facing consumable supporting edge process control.
Core functions include:
The focus ring directly influences wafer edge process behavior.
Key performance characteristics include:
Reliable focus ring performance is critical to maintaining repeatable plasma behavior.
The ring’s stepped profile and thickness are central to process tuning.
Performance attributes include:
Even small dimensional deviations may affect plasma uniformity and edge performance.
The focus ring is exposed to aggressive plasma conditions and high-energy process environments.
Durability characteristics include:
The 2L10-252700-11 may operate alongside related consumables and chamber components including:
Together, these components contribute to plasma stability, chamber protection, and process repeatability.
The 2L10-252700-11 is directly tied to process quality and wafer edge performance.
Potential impacts of wear or degradation include:
Replacing a worn focus ring can restore plasma control and improve process stability.
Continuous plasma exposure may alter ring dimensions over time.
Indicators include:
Material wear can introduce contamination risks.
Symptoms may include:
Worn or incorrect-profile rings may affect process performance.
Indicators include:
To support best performance:
The 2L10-252700-11 (306-T6.5 STEP LAB) is a Tokyo Electron OEM focus ring.
Key considerations:
It refers to a 306 mm class focus ring with a 6.5 mm thickness and a stepped profile, all of which influence plasma behavior and edge process control.
It shapes electric field and plasma density behavior at the wafer perimeter, supporting more uniform etch or deposition performance.
Thickness affects plasma sheath formation, ion distribution, and edge process behavior. Small deviations can materially impact process uniformity.
The stepped geometry is engineered for process-specific plasma interaction and can influence edge tuning and chamber performance.
Typical indicators include:
Yes. Degraded focus rings can contribute to edge defects, variability, reduced process margins, and potential yield loss.
Replacement depends on process chemistry, plasma intensity, wear rates, and preventive maintenance schedules. Monitoring edge performance is critical.
Yes. ESCT supports dimensional, material, and compatibility verification aligned with OEM requirements.
Incorrect geometry can disrupt plasma distribution, alter process tuning, and increase risk of non-uniform processing or yield excursions.
