Alumina That Finishes Strong

We supply powders and beads for the chemical mechanical polishing slurry process, optical polishing, and other surface preparation needs. Every batch is built to meet highly specific and stringent requirements to ensure planarity, low defectivity, and high yield.

The Challenge:
Consistency At And In The Surface

In polishing, repeatability matters. Semiconductor CMP must be ultra-pure, precisely sized, chemically compatible, and highly consistent. These properties directly impact surface quality, yield, and tool uptime in advanced wafer fabrication.

How We Help:
High-Purity Alumina For Optimal Surface Performance

We build alumina formats designed for polishing systems, from alumina polishing slurries to optical and ceramic finishing. PolarGuard™ alumina meets 4N and 5N purity standards, minimizing metal contaminants like Fe, Na, and Si that can compromise device performance. This protects against ionic contamination and supports defect-free surfaces, critical in sub-10nm nodes.

Moreover, we work with customers to tailor surface characteristics (e.g., charge, dispersibility, functionalization) to ensure compatibility with specific slurry chemistries, helping optimize selectivity and planarity. PolarGuard is manufactured using a lean, low-emission, high-consistency process with full traceability. Every batch is tested, qualified, and accompanied by detailed specifications and COAs to support fast fab qualification.

Frequently Asked Questions

A: In the chemical mechanical polishing process, high-purity alumina ensures consistent removal rates and minimizes surface defects. Its low contamination levels and controlled particle size help maintain uniformity across wafers and reduce variability in precision applications.

A: Our powders are used in chemical mechanical polishing (CMP), precision optical polishing, and other advanced surface finishing applications that require low-defect, high-uniformity results.

A: We offer tight particle size distributions in submicron ranges to ensure smooth finishes and reduced scratching. Custom PSDs can be developed to match specific slurry or pad conditions.

A: Yes. Our materials are designed for low metallic impurity levels to avoid surface damage and maintain uniform removal rates, critical in semiconductor use.

A: Absolutely. We work with customers to align on purity, particle size, and distribution specs to support their exact CMP or surface prep conditions.

A: We primarily offer powder formats for polishing, optimized for slurry dispersion and stable performance. Technical documentation is provided with every batch.
