The DISCO DFG8560 wafer grinder is a fully automatic semiconductor wafer grinding system designed for 300mm wafer thinning and precision back grinding applications.

Developed by DISCO Corporation, a leading semiconductor processing equipment manufacturer, the DFG8560 is designed to support advanced wafer thinning requirements for modern semiconductor devices, including memory, logic, power semiconductor, and advanced packaging applications.
As semiconductor packages become thinner and more compact, wafer thinning technology has become increasingly important for improving package performance, reducing device thickness, and enabling advanced packaging structures.
What is DISCO DFG8560 Wafer Grinder?
The DISCO DFG8560 is a fully automatic wafer grinding machine used for semiconductor wafer backside grinding processes.
During semiconductor manufacturing, wafers are often thinned after front-end fabrication and before packaging. The grinding process removes excess silicon thickness from the backside of the wafer while maintaining strict thickness uniformity.
The DFG8560 supports 300mm wafer processing and is designed for high-volume semiconductor manufacturing environments.
DISCO developed the DFG8560 as a successor to the DFG800 series, maintaining established grinding performance while improving equipment weight, operation, and thin wafer processing capability.:contentReference[oaicite:1]{index=1}
Why Wafer Thinning is Important in Semiconductor Manufacturing
Modern semiconductor devices require thinner packages and higher integration density. Wafer thinning is a key process that enables:
Thinner semiconductor packages
Improved thermal performance
Stacked die packaging
3D semiconductor integration
Advanced memory packaging
Without precise backside grinding, wafer thickness variation can affect:
Package reliability
Die strength
Assembly yield
Electrical performance
DISCO DFG8560 Grinding Technology
300mm Wafer Grinding Capability
The DFG8560 supports Φ300mm semiconductor wafers, making it suitable for modern high-volume semiconductor production.
The system can also support 200mm and 300mm wafers when using a universal chuck table configuration.:contentReference[oaicite:2]{index=2}
Ultra Thin Wafer Grinding
One of the key advantages of DFG8560 is its capability for ultra-thin wafer processing.
Optimized grinding and wafer handling parameters allow stable grinding performance for wafer thicknesses below 100μm.
Two-Axis Grinding System
The DFG8560 uses a two-axis grinding configuration designed to improve grinding stability and thickness accuracy.
Matching grinding points between Z1 and Z2 axes helps reduce total thickness variation and wafer-to-wafer variation.
Diamond Grinding Wheel Technology
The system uses precision diamond grinding wheels for semiconductor wafer backside processing.
Grinding wheel performance directly affects surface quality, grinding efficiency, and wafer damage control.
DISCO DFG8560 DBG Process Capability
The DFG8560 supports DBG (Dicing Before Grinding) process integration.
DBG is an advanced wafer thinning method where wafer dicing is performed before grinding. This approach helps reduce wafer damage and improve thin die quality.
The DFG8560 can also be integrated with DISCO polishing systems such as DFP8160 for inline wafer processing solutions.:contentReference[oaicite:3]{index=3}
