The 716-044863-001(U1) EDGE RING (400ESC) is a high-performance plasma-facing consumable used in Lam Research semiconductor processing equipment to support plasma confinement, wafer edge conditioning, and process uniformity in advanced etch and plasma-processing applications.
Installed around the wafer perimeter on compatible 400 mm Electrostatic Chuck (ESC) configurations, the edge ring helps shape and stabilize the plasma environment near the wafer edge. By controlling plasma distribution and minimizing edge effects, the component plays a critical role in maintaining uniform process performance, reducing edge-related variability, and improving overall wafer yield.
Because edge rings operate under continuous exposure to plasma, reactive gases, ion bombardment, RF energy, and thermal cycling, they are considered consumable wear components. Over time, erosion, surface degradation, contamination buildup, and dimensional changes can impact chamber performance and process consistency. The 716-044863-001(U1) is engineered to deliver reliable plasma-facing performance and stable chamber operation throughout its service life.
The ESCT equivalent part number for this component is ES2099-005, 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 716-044863-001(U1) functions as a critical plasma-management component.
