The 3D10-202375-21 CEL, OUTER (TE-349-LABY-GND FLAT) is a precision-engineered chamber component used in Tokyo Electron (TEL) semiconductor equipment to support electrical grounding, plasma confinement, and stable chamber operating conditions during advanced semiconductor manufacturing processes.
Installed within the chamber architecture, the outer cell assembly functions as part of the plasma control and grounding structure, helping maintain consistent electrical characteristics and chamber geometry throughout wafer processing. In semiconductor applications where plasma stability, electrical field control, and process repeatability directly impact yield, maintaining the integrity of chamber grounding components matters.
Because outer cell assemblies operate under continuous plasma exposure, RF energy, thermal cycling, vacuum conditions, and aggressive process chemistries, erosion, surface degradation, contamination buildup, dimensional drift, or grounding performance degradation can gradually affect chamber performance. The 3D10-202375-21 is engineered to provide reliable operation under demanding fab production environments.
The ESCT equivalent part number for this component is ES7099-078, 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 functions as a critical chamber support and grounding component.
