Ring, F-8SO-SI-260-3.4A (325-10) for TEL systems

High-purity silicon focus ring for plasma confinement, wafer edge control, and process uniformity

The 1D10-350647-M2 RING, F-8SO-SI-260-3.4A (325-10) is a precision-engineered silicon focus ring used in Tokyo Electron (TEL) semiconductor processing equipment to support plasma confinement, stabilize wafer edge conditions, and improve process uniformity during advanced plasma etch applications.

Installed around the wafer process zone, the focus ring helps shape the plasma environment near the wafer perimeter, controlling ion distribution and electrical field behavior for consistent etching performance across the wafer surface. In semiconductor manufacturing environments where critical dimension control, profile accuracy, and yield optimization matter, maintaining focus ring integrity is critical to process success.

Because focus rings are continuously exposed to plasma, RF energy, thermal cycling, and aggressive process chemistries, they gradually experience erosion and wear over time. The 1D10-350647-M2 is designed to provide stable chamber performance and repeatable process conditions throughout its operational life.

The ESCT equivalent part number for this component is ES7099-194, supplied as a 2nd Source NEW OEM-compatible replacement designed to meet form, fit, and functional requirements aligned with the original TEL component.

Functional role within TEL systems

The 1D10-350647-M2 functions as a critical plasma-management component.

Core functions include:

  • Supporting plasma confinement around the wafer edge
  • Improving process uniformity across the wafer surface
  • Stabilizing plasma density and ion distribution
  • Reducing edge-related process variation
  • Supporting repeatable chamber performance
  • Contributing to wafer yield and process consistency

In TEL plasma-processing systems, focus rings commonly operate alongside electrodes, ground rings, ESC assemblies, chamber liners, and other plasma-facing consumables.
