Key Features

1. Ultra-High Purity Synthetic Quartz
   Made from 99.99% synthetic fused silica (SiO₂), ensuring minimal impurities (<1 ppm) for contamination-sensitive processes in semiconductor and photonic fabrication.

2. Double-Side Polished Precision
   Both surfaces polished to sub-5 Å (angstrom) roughness, enabling defect-free thin-film deposition, lithography, and optical coatings.

3. Precision Dicing Technology
   Laser or mechanical dicing achieves micron-level accuracy for chip dimensions, ideal for microelectronics, MEMS, and sensor arrays.

4. Exceptional Thermal Stability
   Near-zero thermal expansion (CTE: 0.55 x 10⁻⁶/°C) prevents warping during high-temperature processes like annealing or bonding.

5. Chemical and Plasma Resistance
   Withstands aggressive etchants, solvents, and plasma environments, ensuring longevity in harsh semiconductor workflows.

6. SEMI Compliance
   Meets SEMI standards for flatness, purity, and defect density, compatible with automated handling systems in cleanrooms.
