Silicon Wafer Glass Rare Earth Polishing Slurry Chemical Mechanical Planarization CeO2

Polishing Slurry for Silicon Wafer Polishing

Description

Achieve atomic-level planarity and superior surface integrity with our Series Cerium Oxide (CeO₂) Polishing Slurries. Specifically engineered for Chemical Mechanical Planarization (CMP) in advanced semiconductor manufacturing, our slurries are optimized for the transition to smaller process nodes. 

By leveraging the unique chemical-mechanical synergy of high-purity ceria, our formulations deliver high material removal rates (MRR) while maintaining the ultra-low defectivity required for next-generation logic and memory devices.

Performance Excellence

Nanometer-Level Planarity: Engineered to produce ultra-smooth, high-gloss surfaces with root-mean-square roughness as low as 0.06 nm to 0.32 nm on silicon and dielectric films.

High Selectivity & Removal Rates: Optimized for Shallow Trench Isolation (STI) and Interlayer Dielectric (ILD) applications, delivering bulk oxide removal rates exceeding 500 nm/min.

Precision: Designed to meet stringent defectivity requirements for advanced technology nodes, minimizing surface scratching.

Advanced Suspension Stability: Proprietary particle engineering and stabilizers ensure uniform dispersion and prevent agglomeration, reducing the risk of micro-scratches caused by oversized particles.

Sustainable Resource Technology: Our formulations align with industry initiatives, offering improved resource efficiency and compatibility with recycling technologies to reduce total cost of ownership.

Q&A

1. What is rare earth polishing powder?

Rare earth polishing powder is a high-purity compound used for polishing optical components, semiconductor wafers, and delicate surfaces like glass and lenses. It delivers a smooth, high-clarity finish without damaging the material.

2. How do I choose the right rare earth polishing powder for my application?

To select the ideal polishing powder, consider factors like the material you’re polishing, the required finish, and specifications like particle size and purity. Our sales team is available to help you choose the perfect product for your needs.

3. How should I store  rare earth polishing powder?

Store in a cool, dry place, away from moisture and direct sunlight. Keep the powder in airtight containers to prevent contamination and maintain its effectiveness. With proper storage, it typically lasts 1-2 years.

4. Do you provide customized rare earth formulations?

Yes, we offer custom rare earth polishing powders and slurries, tailored to meet your specific needs, including adjustments to particle size, chemical composition, or slurry consistency.
