FOSB (Front Opening Shipping Box) for Semiconductor Wafer Transport
What is FOSB?
FOSB (Front Opening Shipping Box) is a high-performance semiconductor wafer shipping container designed for secure storage and long-distance transportation of 200mm and 300mm wafers.
The FOSB wafer box features a front-opening door structure that ensures safe robotic loading and unloading while maintaining ultra-clean internal conditions. It is widely used in semiconductor fabs, wafer foundries, packaging houses, and international wafer logistics.
Compared with traditional wafer carriers, FOSB shipping boxes provide better sealing, improved contamination control, and enhanced mechanical protection during transportation.
Key Features of FOSB Wafer Shipping Box
1. SEMI Standard Compliance
Our FOSB wafer shipping box complies with SEMI standards, ensuring compatibility with automated wafer handling systems and industry-standard load ports.
2. High Cleanliness Performance
2. High Cleanliness PerformanceCleanroom compatible: Class 1 – Class 100
Low particle generation material
Precision-molded wafer slots
Excellent sealing performance
FOSB is ideal for contamination-sensitive semiconductor applications.
3. ESD Safe & Anti-Static Options
We offer both natural PP and ESD-safe FOSB shipping boxes. The anti-static version protects wafers from electrostatic discharge damage during storage and transportation.
4. Superior Mechanical Protection
Shock-resistant outer structure
Secure wafer slot alignment
Reduced wafer edge chipping risk
Strong locking door mechanism
The FOSB wafer box ensures maximum wafer integrity during international shipping.
5. Reusable & Durable
Manufactured from high-purity polypropylene (PP), our FOSB containers support multiple shipping cycles, reducing long-term packaging costs.

FOSB vs FOUP – What’s the Difference?
While both FOSB and FOUP are front-opening wafer carriers:
FOSB is mainly designed for wafer shipping and external logistics.
FOUP is primarily used inside semiconductor fabrication facilities for automated production processes.
If you require a wafer shipping container for transportation rather than in-fab automation, FOSB is the more cost-effective and practical choice.
