​​6Inch Vertical Wafer Cassette Box Wafer Transport Container

​​6Inch Wafer Cassette Box Overview​​


​​6Inch Vertical Wafer Cassette Box Wafer Transport Container


The ​​6-inch wafer cassette box​​ is a high-purity, precision-molded container designed for ​​safe storage, transportation, and handling​​ of 6-inch (150mm) semiconductor wafers. It serves as a ​​critical auxiliary component​​ in wafer fabrication lines, ensuring protection against ​​particulate contamination, mechanical shock, electrostatic discharge (ESD), and chemical exposure​​ during intermediate storage and intra-fab logistics. Manufactured materials​​ (e.g., PFA, PP, or conductive polymers), it features a ​​modular slot design​​ with ​​graduated pitch alignment​​, enabling seamless integration with ​​automated handling equipment​​ (e.g., robots, AGVs) and process tools (e.g., etching, CVD, metrology).



​​6Inch Wafer Cassette Box Key Advantages & Features​​

1. Contamination Control​​: ​Ultra-low particle generation​​ (<0.5 particles/cm³ @ 0.2μm) and ​​chemical resistance​​ (acids/alkalis) prevent wafer surface degradation.


​​2. ESD Protection​​: ​​Surface resistivity 10⁶–10⁹ Ω/sq​​ avoids charge buildup and circuit damage.


​​3. Mechanical Safety​​:​​ Rigid yet lightweight structure​​ with shock-absorbing features minimizes breakage during transport.


​​4. Automation Compatibility​​: ​​Standard dimensions​​ and ​​RFID/barcode tags​​ enable seamless AMHS (Automated Material Handling System) integration.


​​5. Thermal Stability​​: Withstands ​​-40°C to 150°C​​ for use in cleanrooms and process environments.


Primary Application Scenarios​​ of 6Inch Wafer Cassette Box

  • Wafer Fabrication Lines​​: Intermediate storage between ​​diffusion, etching, and deposition tools​​.
  • ​​Metrology & Inspection​​: Holding wafers during ​​CD-SEM, overlay, and defect inspection​​.
  • ​​Back-End Packaging​​: Transporting wafers to ​​dicing, bonding, and testing facilities​​.
  • ​​R&D Labs​​: Prototyping and low-volume processing requiring ​​manual or automated handling​​.
