2/4/6-Inch 25-Slot Wafer Cassette Carrying Tray: Secure Storage for Silicon, Sapphire, and SiC Substrates

Introduction
In industries like semiconductor fabrication, optoelectronics, and power electronics, efficient and secure substrate storage is paramount. The 2/4/6-Inch 25-Slot Wafer Cassette Carrying Trayaddresses the growing demand for versatility and scalability, offering compatibility with multiple wafer sizes (2”, 4”, 6”) and robust protection for Silicon (Si), Sapphire, and Silicon Carbide (SiC) substrates. This article highlights its design, applications, and advantages for modern manufacturing workflows.

Key Features of the 25-Slot Multi-Size Wafer Tray

1. Multi-Size Compatibility
   Accommodates 2-inch, 4-inch, and 6-inch wafers in a single cassette, eliminating the need for multiple trays and simplifying inventory management.

2. High-Capacity Design
   25 slots maximize storage density, ideal for bulk handling in high-volume production or research environments.

3. Anti-Contamination & Anti-Static Materials
   Constructed from ultra-clean polycarbonate or PEEK, ensuring minimal particle generation and static dissipation to protect sensitive substrates.

4. Chemical and Thermal Resilience
   Resists degradation from acids, solvents, and high temperatures (up to 150°C), suitable for harsh fabrication processes.

5. Ergonomic and Automation-Ready
   Features secure grip handles and compatibility with robotic arms (SMIF/FOUP systems) for seamless integration into automated production lines.

6. SEMI-Compliant Standards
   Meets SEMI/FED-STD-209E cleanliness requirements, ensuring reliability in ISO-classified cleanrooms.

Primary Applications

• Semiconductor Fabs: Safely transports wafers during CVD, PVD, or ion implantation processes.

• SiC Power Device Production: Protects brittle SiC substrates in high-temperature manufacturing.

• LED and Display Manufacturing: Organizes Sapphire wafers for epitaxy and lithography stages.

• R&D Facilities: Streamlines substrate handling for experimental batches across multiple sizes.

Why Opt for a 25-Slot Multi-Size Cassette?

• Cost Efficiency: Reduces tray purchases by supporting 2”, 4”, and 6” wafers in one unit.

• Space Optimization: Vertical stacking capability saves cleanroom or storage space.

• Damage Prevention: Precision-molded slots prevent wafer shifting, minimizing micro-cracks and scratches.

• Future-Proofing: Adapts to evolving production needs, from legacy 2-inch wafers to advanced 6-inch SiC substrates.

Conclusion
The 2/4/6-inch 25-slot wafer cassette carrying tray is a game-changer for industries requiring flexible, high-capacity substrate storage. Its multi-size compatibility, rugged design, and compliance with industry standards make it indispensable for boosting productivity and safeguarding valuable Silicon, Sapphire, and SiC wafers in demanding environments.
