0200-35223 Ceramic Ring
The AMAT 0200-35223 Ceramic Ring is a high-precision semiconductor ceramic component designed for advanced plasma etch and deposition environments. Widely used in semiconductor processing systems, this ceramic ring helps regulate plasma behavior within the chamber while supporting stable RF field distribution and reducing contamination risks during wafer fabrication processes. At Semixlab, we specialize in manufacturing and supplying semiconductor-grade ceramic spare parts engineered for high-density plasma applications, advanced etch chambers, and critical wafer processing environments. Looking forward to your inquiry.
Description
The AMAT 0200-35223 Ceramic Ring belongs to the category of semiconductor plasma chamber ceramic rings commonly integrated into advanced etch and deposition systems. Structurally, it is designed as a precision-engineered ring component positioned near the wafer processing region, typically around the electrostatic chuck (ESC), plasma confinement area, or chamber edge transition zone.
Although compact in appearance, its role inside the chamber is highly important. During plasma processing, the wafer edge region experiences complex interactions between RF fields, ion trajectories, and plasma density distribution. Without proper chamber tuning, these interactions can lead to process instability, edge profile inconsistency, and non-uniform etching or deposition behavior.
The ceramic ring acts as a functional plasma-control interface between the wafer and surrounding chamber structures. By influencing local electric field distribution and stabilizing plasma conditions near the wafer edge, it helps improve overall chamber process consistency and wafer yield.
Core Functions of the 0200-35223 Ceramic Ring
One of the most important functions of the 0200-35223 Ceramic Ring is plasma edge regulation. In advanced semiconductor processes, plasma density near the wafer edge can significantly affect critical dimension control, profile uniformity, and overall process stability. The ceramic ring helps manage plasma distribution near the edge region, reducing process deviations and improving wafer uniformity.
The component also contributes to RF field stabilization inside the chamber. Because plasma behavior is closely related to impedance distribution and sheath formation, the geometry and dielectric properties of the ceramic ring directly influence ion energy distribution and plasma coupling efficiency. This makes the ceramic ring an important RF-engineered chamber component rather than a passive mechanical structure.
Another critical function is chamber protection. During high-density plasma operation, chamber walls and nearby components are exposed to aggressive ion bombardment and reactive plasma species. The ceramic ring acts as a protective barrier, reducing direct plasma exposure to sensitive chamber structures and helping extend equipment service life.
In addition, the ceramic ring supports particle reduction strategies within the chamber. High-purity ceramics with optimized surface finishes help reduce contamination risks associated with sputtering, erosion, and outgassing, which is especially important in advanced semiconductor nodes where particle tolerance becomes increasingly strict.
