Horizontal Wafer Carrier Box 8" 12" Secure Transporter RoHS

Horizontal Wafer Carrier – Precision Handling for Semiconductor Manufacturing

 
The Horizontal Wafer Carrier represents a critical innovation in semiconductor manufacturing, designed to safely transport and store delicate wafers (150mm to 450mm) during fabrication processes. Engineered for cleanroom compatibility and process stability, these carriers utilize advanced materials and precision engineering to minimize particle generation while maximizing wafer throughput in deposition, etching, and inspection equipment.
 
Unlike traditional vertical carriers, horizontal designs provide:
 

• Upper & Lower Cover Inner Ring Design – Minimizes wafer lateral movement while preventing edge contact, ensuring scratch-free handling.

• Reinforced Lower Inner Ring with Finger Grips – Enhances shock resistance and provides compatibility with automated equipment interfaces.

• 4-Point Locking System & Impact-Resistant Outer Ring – Protects wafers during transit with structural robustness.

• Recessed Surface Lettering – Prevents tearing of HDPE packaging bags during logistics.

Q&A

Q1: Why choose horizontal over vertical carriers?
A1: Horizontal orientation recreases wafer deflection by 60% (per SEMI E158-1119), critical for <5nm node processing.
 
Q2: How do you prevent wafer sticking?
A2: Our nano-patterned pocket surfaces reduce contact area by 85% versus standard designs.
 
Q3: What's the maintenance schedule?
A3: 50,000 cycles before pad replacement; full refurbishment every 200k cycles.
 
Q4: How do you handle wafer breakage?
A4: Fragmented wafer containment pockets prevent cross-contamination.
 
Q5: Can carriers be used in vacuum chambers?
A5: Yes - special outgassing-optimized versions available (<10⁻⁶ Torr·L/sec).
