概要（Overview）

The Disco DFG841 is designed for device manufacturers and can handle wafers with a maximum diameter of 200mm (ø4"ø8"). It uses a two-wheel grinding process (rough and fine grinding) for low TTV applications. It features a two-spindle, two-chuck table configuration and an advanced vacuum robot arm for thin wafer handling. The robot arm vacuum corrects thin-ground wafers to the required flatness for trouble-free handling. All wafer transportation is conducted in a safe and secure environment. The machine is designed for ease of maintenance and has a lightweight construction.
