Carl Zeiss AG has shattered precision records with quantum-stabilized wool wheels producing 0.3Å surface roughness on extreme ultraviolet lithography mirrors – surpassing theoretical limits by 40%. These cryogenic wool polishing pads operate at -269°C to eliminate thermal drift during semiconductor optics manufacturing.
Technical Milestones
- Helium-Cooled Spindles: Maintain 0.001K thermal stability
- Femtosecond Laser Calibration: Real-time surface mapping
- Non-Contact Polishing: Magnetic levitation maintains 50μm gap

Scientific Validation
“At this scale, atomic forces dominate. The nano-porous wool fibers prevent quantum tunneling effects,” explains Nobel laureate Dr. Klaus von Klitzing. PTB (German Metrology Institute) has certified the process as meeting VDI/VDE 2655 Part 1.4 standards.
Market Shift
- Semiconductor optics polishing market to reach $4.3B by 2028 (Yole Développement)
- 100% of EUV mirror production now uses quantum wool polishing technology
