Gentle wafer dicing | Industrial Laser Solutions

Edge grinding can be performed before or after back grinding. Figure 4 shows a 725-µm thick silicon wafer that has been grooved before back grinding. When the wafer becomes thin (after back grinding), the knife-edge containing micro-cracks is separated from the rest of the wafer. A 75-µm nozzle has been used and the grooving speed was 50 mm/s.
