The 2L10-252701-11 RING, GND (L) SI STEP V2 is a precision-engineered plasma-facing electrical component used in Tokyo Electron (TEL) semiconductor equipment to support RF grounding integrity, plasma stability, and repeatable chamber performance in demanding wafer processing environments.
Installed within the chamber process architecture, this ground ring helps establish controlled electrical grounding paths that influence plasma behavior, field distribution, and process boundary stability. In semiconductor applications where plasma uniformity, RF coupling, and chamber electrical balance directly affect etch precision, deposition consistency, and yield performance, reliable ground ring condition is critical.
Because ground rings operate under sustained plasma exposure, RF electrical stress, ion bombardment, thermal cycling, and reactive chemistries, erosion, dimensional drift, conductive surface degradation, or contamination buildup can contribute to unstable plasma behavior, electrical imbalance, particle generation, or increased maintenance frequency. The 2L10-252701-11 is engineered to support stable chamber electrical performance under demanding fab production conditions.
The ESCT equivalent part number for this component is ES7099-118, supplied as a 2nd Source NEW OEM-compatible replacement designed to meet form, fit, and functional requirements aligned with the original OEM part.
The 2L10-252701-11 functions as a critical plasma control and RF grounding component.
