The 2L10-251316-11 CEL, INNER TP (NEST) V2 is a precision-engineered chamber support component used in Tokyo Electron (TEL) semiconductor equipment to support wafer positioning stability, internal process hardware alignment, and repeatable chamber performance in advanced semiconductor manufacturing environments.
Installed within the chamber’s internal support architecture, the Inner TP (Nest) assembly functions as a structural and positioning interface that helps maintain accurate placement of process-critical hardware while supporting stable wafer handling and chamber operating conditions. In semiconductor processes where positional accuracy, mechanical stability, and repeatable chamber geometry directly affect yield and process consistency, so nest component condition has to stay good.
Because nest assemblies operate under sustained thermal cycling, mechanical loading, vibration exposure, process-induced stress, and contamination-sensitive conditions, wear, dimensional drift, alignment degradation, or surface damage can contribute to positioning instability, process variation, maintenance challenges, or unplanned downtime. The 2L10-251316-11 is engineered to support stable chamber integration and reliable subsystem performance under demanding fab conditions.
The ESCT equivalent part number for this component is ES7099-125, supplied as a 2nd Source NEW OEM-compatible replacement designed to meet form, fit, and functional requirements aligned with the original TEL part.
The 2L10-251316-11 functions as a critical positioning and support component within the chamber architecture.
Core functions include:
In many TEL platforms, the Inner TP (Nest) assembly may operate alongside related chamber hardware such as focus rings, ground rings, ESC assemblies, support plates, lift mechanisms, and plasma-facing consumables that collectively support process stability and chamber reliability.
