Disco DAG810 is a single axis automatic wafer grinder that can grind wafers up to 300mm diameter. With one air bearing grind spindle and one vacuum chuck mounted on a high precision mechanical lower spindle this grinder has a relatively small footprint of only 11 square feet. This grinder can perform either standard in-feed (plunge) grinding or optional creep feed grinding.
With optimized grinding of 200mm SEMI grade silicon wafers, the DAG810 is capable of:
Thickness control of ± 1.5 micron (WTW)
TTV across the wafer of ≤ 1.5 micron
