The 716-081665-842 RING, C-SECTION10 SLOT, POLY SI is a precision-engineered process ring used in Lam Research semiconductor equipment to support plasma process stability, wafer edge conditioning, and chamber performance consistency in Poly-Si deposition and etch applications.
Installed within the process chamber as part of the wafer processing environment, this C-section 10-slot ring helps manage plasma distribution behavior, edge effects, gas flow dynamics, and process zone conditioning critical to uniform wafer treatment. In semiconductor manufacturing environments where tight process control and repeatable chamber conditions matter, the condition and dimensional stability of process rings can directly influence yield, repeatability, and tool uptime.
Because chamber rings operate under sustained plasma exposure, thermal cycling, particle-sensitive conditions, and reactive chemistries, wear, coating erosion, dimensional drift, or contamination buildup can contribute to plasma instability, edge non-uniformity, defect risk, or increased maintenance frequency. The 716-081665-842 is engineered to support stable chamber conditions and reliable performance under demanding fab production environments.
The 716-081665-842 functions as a critical chamber conditioning and plasma management component.
