Product Description

We manufacture high-performance Alumina Ceramic Rings specifically engineered for critical applications in semiconductor plasma processing equipment. Made from High-Purity Alumina A998 (99.8%), our components provide unmatched plasma resistance and reliability in demanding etch and CVD chambers.

Product Overview

Our ceramic ring series includes, but is not limited to:

Collar Edge Rings / Dep Rings
Focus Rings
Chamber Inserts & Liners
Other Customized Process Kit Components

These components are precision-engineered to meet the stringent requirements of 200mm and 300mm semiconductor fabrication tools, ensuring process stability and yield.

Key Material Properties & Advantages

Feature	Benefit for Your Process
Exceptional Plasma Resistance	Extends Service Life: Withstands aggressive plasma environments in etch and deposition chambers, reducing particle generation and frequency of replacement.
High Dielectric Strength	Superior Electrical Insulation: Preents current leakage and arcing, ensuring process stability and protecting sensitive chamber components.
High Corrosion Resistance	Chemically Inert: Resists corrosion from halogen-based (e.g., CF₄, Cl₂) and other process gases, maintaining geometric integrity and process consistency.
High Purity (A998)	Minimizes Contamination: 99.8% alumina content ensures no metallic contamination, which is critical for high-purity wafer manufacturing and high yield rates.
Excellent Mechanical Strength	Durable and Reliable: Maintains structural integrity under thermal and mechanical stress, ensuring long-term performance and reducing unscheduled downtime.

Primary Applications in Semiconductor Manufacturing

Our ceramic rings are vital consumables and components within plasma chambers:

Etch Systems: Used as Focus Rings and Chamber Liners in Dielectric and Conductor Etch tools to precisely control plasma density and protect chamber walls.
CVD/PVD Systems: Serve as Collar Edge Rings and Inserts to define the processing environment and prevent unwanted deposition.
Plasma Cleaning Chambers: Act as durable Liners that resist erosion from O₂ or NF₃ plasmas, extending maintenance cycles.
