Focus Ring 8/MIN/CL for Plasma Uniformity and Chamber Edge Control, Tokyo Electron Platforms
The 3D10-250576-21 (RING FOCUS 8/MIN/CL) is a precision-engineered plasma-facing focus ring used within Tokyo Electron semiconductor processing systems, designed to support plasma confinement, wafer edge control, and repeatable process uniformity in advanced etch applications.
Positioned around the wafer on the electrostatic chuck (ESC), the focus ring helps shape electric field behavior and plasma density near the wafer perimeter, supporting consistent edge process conditions while helping protect chamber hardware from direct plasma exposure. Its geometry and material properties are engineered to support specific chamber and recipe conditions where plasma behavior at the edge can materially influence critical dimension control, process repeatability, and yield.
In high-energy plasma environments, focus ring condition directly affects process stability. Wear, erosion, dimensional drift, or incorrect profile selection can contribute to edge non-uniformity, particle generation, process drift, and increased maintenance frequency. The 3D10-250576-21 is designed to support reliable plasma-facing performance under sustained cleanroom production conditions.
The 3D10-250576-21 functions as a critical plasma-facing consumable supporting wafer edge plasma control.
Core functions include:
The focus ring directly influences wafer edge process behavior.
Key performance characteristics include:
Reliable focus ring performance is critical to repeatable plasma behavior and yield protection.
The geometry of the focus ring is central to plasma tuning.
Performance attributes include:
Even small dimensional changes can materially affect plasma behavior and process results.
The focus ring operates under aggressive plasma exposure and must sustain material integrity over long duty cycles.
Durability characteristics include:
The 3D10-250576-21 may operate alongside related chamber components including:
Together these components support chamber protection, plasma stability, and repeatable process performance.
The 3D10-250576-21 is directly tied to process quality and chamber stability.
Potential impacts of wear or degradation include:
Replacing a worn focus ring can restore plasma control and improve process repeatability.
Continuous plasma exposure can alter ring dimensions over time.
Indicators include:
Material wear can introduce contamination risk.
Symptoms may include:
Degraded focus rings may affect process behavior near the wafer perimeter.
Indicators include:
To support best performance:
The 3D10-250576-21 (RING FOCUS 8/MIN/CL) is a Tokyo Electron OEM part.
Key considerations:
It supports plasma confinement and wafer edge control, helping maintain process uniformity and stable chamber performance.
It shapes electric field and plasma density behavior at the wafer perimeter, directly influencing edge process conditions.
Geometry influences plasma interaction, ion distribution, and process tuning. Even small deviations can impact uniformity.
Common indicators include:
Yes. Degradation can contribute to edge defects, variability, and reduced process control margins.
Yes. Focus rings are typically managed as plasma-facing consumables and replaced based on wear thresholds or preventive maintenance intervals.
Yes. ESCT supports dimensional, material, and compatibility verification aligned with OEM requirements.
Depending on availability, associated components such as 2L10-252700-11, 2L10-251877-11, and related chamber hardware may also be supported.
Incorrect geometry can disrupt plasma behavior, alter process tuning, and increase risk of non-uniform processing or yield excursions.
