Wafer Dicing Process in Semiconductor Manufacturing
Wafer dicing is one of the key backend semiconductor processes.
After semiconductor wafers complete fabrication and thinning, the wafer contains hundreds or thousands of individual dies connected together.
The dicing process separates these dies for:
Die bonding
Wire bonding
Flip chip assembly
Advanced packaging
A high-quality dicing process must achieve:
Low chipping
Low crack generation
High dimensional accuracy
Stable cutting quality
DISCO DFD6341 Key Technologies
Fully Automatic Wafer Handling
The DFD6341 integrates automatic wafer loading, alignment, cutting, cleaning, drying, and unloading.
The operation flow reduces manual handling and improves production consistency.
Dual Spindle Dicing System
The equipment uses a facing dual spindle configuration.
Dual spindle cutting reduces processing time by allowing optimized cutting operations and shorter spindle distance.
This design improves throughput compared with traditional single spindle dicing systems. :contentReference[oaicite:3]{index=3}
High-Speed Axis Control
The DFD6341 incorporates axis technology developed from DISCO 300mm dicing platforms.
The X-axis return speed can reach 1,000 mm/s, while improved acceleration and deceleration performance increases high-speed movement range. :contentReference[oaicite:4]{index=4}
High-Speed Flash Alignment
An optional flash alignment system combines xenon flash lighting and high-speed CCD technology.
This allows wafer alignment without stopping the chuck table, reducing alignment time and improving productivity. :contentReference[oaicite:5]{index=5}
Integrated Cleaning and Drying
After cutting, wafers are transferred to the spinner unit for cleaning and drying.
This removes cutting debris and prepares wafers for downstream packaging processes.
