The 3D10-350067-11 (SI-SHIN) RING PROTECTION (TE-RP470) is a precision-engineered silicon plasma-facing consumable used in Tokyo Electron (TEL) semiconductor equipment to protect critical chamber hardware from plasma exposure, minimize component wear, and support stable process performance in advanced semiconductor manufacturing environments.
Installed within the chamber process zone, the protection ring serves as a sacrificial wear component designed to shield adjacent chamber hardware from direct plasma interaction, ion bombardment, and process-induced erosion. In semiconductor applications where chamber geometry, contamination control, and plasma stability directly influence yield and process repeatability, maintaining a properly functioning protection ring is critical.
Because protection rings operate under continuous plasma exposure, thermal cycling, reactive process chemistries, and high-energy ion environments, erosion, dimensional wear, particle generation, or surface degradation can gradually affect chamber performance and increase maintenance requirements. The 3D10-350067-11 is engineered to help preserve chamber integrity while supporting stable wafer processing conditions.
The ESCT equivalent part number for this component is ES7099-043, supplied as a 2nd Source NEW OEM-compatible replacement designed to meet form, fit, and functional requirements aligned with the original TEL component.
The 3D10-350067-11 functions as a critical chamber protection and plasma-conditioning component.
Core functions include:
In many TEL process platforms, protection rings operate alongside focus rings, ground rings, electrodes, chamber liners, ESC assemblies, and other plasma-facing consumables to support overall chamber stability.
The protection ring serves as a sacrificial barrier between the plasma and critical chamber surfaces.
