The back grinding process of the wafer is to put a layer of film on the front of the wafer to protect the integrated circuit that has been made, and then use the grinding machine to reduce the thickness. After grinding and thinning the back of the wafer, a damaged layer will be formed on the surface, and the warpage is high, which is easy to break.

Silicon Wafer Specifi cations Diameter The diameter of the silicon wafers are specifi ed either in inches or mm. Although an inch is 25.4 mm, the diameters of wafers in inches are usually multiples of 25.0 mm (e.g. 4 inches = 100 mm), which should be clarifi ed beforehand with the supplier. The tolerance of the diameter is typically +/- 0.5 mm.

In addition, ELID grinding of silicon wafers was done on a horizontal spindle surface grinding machine using a straight type wheel [16], as shown in Fig. 10. This set-up would make it possible to grind a large wafer without using a large grinding wheel. The silicon wafer (workpiece) was held on a rotary table.

Therefore, a modern wafer grinding machine begins with a coarse grinding wheel to get a fast removal of the silicon and at the end follows a fine grinding process step with small grit size grinding wheel. This final process is absolute necessary when thinning down to 50 ?m in order to minimize subsurface damage and stress.

The wafer grinding machine uses a centrally located robot to move a wafer from an input station to a measuring station. Thereafter, the wafer is moved into a grind station and a wash station sequentially. The robot is able to move a wafer from the wash station to either the measuring station for after-grinding measurements or directly to an output station.
