Activated Carbon for Ultrapure Water Production in Electronics and Semiconductor Manufacturing

Cleaner than the water itself.

Ultrapure water is the lifeblood of semiconductor fabrication. Every wafer cleaning, rinsing, and chemical dilution step depends on water that is essentially free of organics, particles, and dissolved ions. In advanced nodes, even ppb-level organic contamination can cause gate oxide defects, pattern collapse, or yield loss. The carbon that polishes this water must be cleaner than the water itself.

The Challenge & PureStar Approach

The Core Challenge: Eliminating self-contamination risk.

Standard activated carbon, even food-grade, can introduce extractable organics, colloidal particles, or metal ions that exceed semiconductor specifications. The manufacturing process must be as pure as the end product: no chemical activants, no acid residues, and absolutely no metal contamination from processing equipment.

Why Choose PureStar?

PureStar's ultrapure water grades are manufactured under strict semiconductor-industry cleanliness protocols with high-temperature steam activation, acid-wash purification, and controlled packaging under cleanroom-compatible conditions. Our low-extractable, low-metal GAC and specialty carbons remove trace organics and TOC without introducing new contaminants. Comprehensive batch certification includes ICP-MS metal analysis and TOC leachate testing, providing the rigorous documentation that fabs require for chemical qualification.

Key Benefits:

• Semiconductor-Grade Cleanliness: Produced via high-temperature steam activation and acid-washing to eliminate chemical activants and residual impurities.
• Zero Self-Contamination: Low-extractable, ultra-low metal formulations ensure trace organics and TOC are removed without introducing secondary pollutants.
• Full Fab Qualification Support: Batch certifications include ICP-MS metal analysis and TOC leachate testing, meeting stringent documentation requirements for advanced node production.
