HESION produces high-quality silicon wafer carriers (Wafer Carrier or Wafer Shipper), specifically designed for the safe, clean, and anti-static storage, transportation, and handling of semiconductor silicon wafers (wafers).
Product Description:
1. Material and Structure:
• Silicon wafer carriers are typically made of high-quality engineering plastics such as polypropylene (PP), as PP has good chemical resistance and anti-static properties.
• The box structure is precisely designed, including multiple slots for securing individual wafers, ensuring that the wafers remain stable during transportation and preventing collisions and scratches.
• Some wafer carriers may have additional anti-static or shock-absorbing materials inside and on the edges to further protect the wafers from electrostatic discharge or physical impact.
2. Anti-static Performance:
• Silicon wafer carriers typically have an anti-static design; the material or surface treatment maintains a surface resistivity between 10^6 and 10^9 ohms/square, ensuring that static charges can dissipate quickly, preventing electrostatic discharge from damaging the wafers.
3. Specifications and Models:
• According to the wafer size, silicon wafer carriers are available in various specifications, such as 4-inch, 6-inch, 8-inch, and 12-inch, corresponding to different wafer diameters.
• Wafer carriers may also have different models, such as FOUP (Front Opening Unified Pod) for 12-inch wafers in advanced semiconductor manufacturing, and wafer carriers in SMIF (Standard Mechanical Interface) systems.
4. Usage and Maintenance:
• Before use, ensure that the wafer carrier is clean and dust-free. It can be opened and closed in a cleanroom environment.
• After placing the wafers in the carrier, ensure that the wafers fit snugly into the slots to prevent shaking during movement.
• For cleaning, use a dedicated cleanroom-grade anti-static cleaner and dust-free cloth to avoid scratching the wafer carrier or introducing contaminants.
5. Applicable Scenarios:
• Silicon wafer carriers are widely used in various stages of semiconductor manufacturing, including storage after wafer cutting, transfer between cleanrooms, and protection during external transportation.
