The 3D10-202375-21(S) CEL, OUTER (TE-349-LABY FLAT) is a critical plasma-facing chamber component used in Tokyo Electron (TEL) semiconductor processing equipment to support plasma confinement, chamber conditioning, and process stability during advanced plasma etch and semiconductor manufacturing applications.
Installed within the chamber assembly, the outer cell serves as an important structural and process-control component that helps maintain chamber geometry, regulate plasma interactions, and protect surrounding hardware from direct process exposure. By contributing to stable chamber conditions, the outer cell helps give repeatable wafer processing, contamination control, and consistent production performance.
Because outer cells operate under continuous exposure to plasma, RF energy, thermal cycling, reactive chemistries, and ion bombardment, they are considered wear components that require periodic inspection and replacement. Surface erosion, dimensional wear, contamination buildup, and material degradation can gradually impact chamber performance and process repeatability.
The ESCT equivalent part number for this component is ES7099-021, supplied as a 2nd Source NEW OEM-compatible replacement designed to meet form, fit, and functional requirements aligned with the original TEL component.
The 3D10-202375-21(S) functions as a critical chamber conditioning and plasma-management component.
Core functions include:
In TEL plasma-processing systems, outer cells commonly operate alongside focus rings, electrodes, ground rings, chamber liners, ESC assemblies, and other plasma-facing consumables.
