High Gloss and No Powder Shedding

Supwafer’s wafer separators deliver critical surface performance with high gloss and no powder shedding, engineered for precision semiconductor processing. The high-gloss finish ensures ultra-smooth wafer contact, preventing micro-abrasions on sensitive substrates like SiC and enhancing inspection accuracy. Its no-powder-shedding design, via wear-resistant materials and precision coatings, eliminates particle contamination—critical for advanced nodes and high-reliability devices—while meeting SEMI cleanroom standards to safeguard yield and process integrity.

Different shapes of wafer separators

Round Wafer Separators

Round Wafer Separators are precision-engineered for 2” to 12” circular wafers, leveraging shape-specific design to minimize stress and ensure uniformity—outperforming multi-shape systems in high-precision workflows.

- Contour-Matched Handling: Circular surfaces distribute pressure evenly, reducing warpage in thin (≤50μm) substrates.

- Radial Control: Optimized concentric separation paths align with dicing saw needs for full-wafer processing.

- Edge Protection: Rounded tooling prevents micro-cracks in brittle materials (e.g., SiC), boosting die yield.

- Standard Compatibility: Pre-calibrated for standard circular sizes, cutting setup time in fabs.

Square Wafer Separators

Square Wafer Separators are specialized for 2” to 5” square substrates, with design elements tailored to their angular geometry—ensuring precise handling where rectangular alignment and edge stability are critical.

- Corner Stress Reduction: Reinforced tooling at corners minimizes chipping in square substrates, a key issue in angular wafer processing.

- Edge-to-Edge Uniformity: Linear separation paths optimize alignment for square-specific dicing patterns, common in display and sensor fabrication.

- Custom Fit for Square Formats: Pre-configured for standard square sizes, cutting setup time in PCB and optoelectronic production lines.

- Rigid Edge Support: Enhanced clamping at straight edges prevents flexing in thin square wafers, vital for GaN-based power device manufacturing.
