The 716-069688-789 WAVE INNER ELECTRODE is a critical plasma-facing component used in Lam Research semiconductor processing equipment to support RF power coupling, plasma generation, and uniform process performance in advanced etch and deposition applications.
Installed within the chamber’s plasma-generation architecture, the inner electrode serves as a primary interface for delivering RF energy into the process environment. By helping control plasma density, ion distribution, and electrical field characteristics, the electrode plays a direct role in maintaining process consistency, critical dimension control, and wafer yield.
Because inner electrodes are continuously exposed to ion bombardment, RF energy, thermal cycling, and aggressive process chemistries, they are considered high-wear components. Erosion, surface degradation, contamination buildup, and dimensional changes can gradually impact chamber performance and process repeatability. The 716-069688-789 is engineered to provide reliable plasma performance and long operational life under demanding semiconductor manufacturing conditions.
The ESCT equivalent part number for this component is ES2099-054, supplied as a 2nd Source NEW OEM-compatible replacement designed to meet form, fit, and functional requirements aligned with the original Lam Research component.
The 716-069688-789 functions as a critical plasma-generation and electrical distribution component.
