For wafers with diameters of 200 mm it is typical to start with a wafer thickness of roughly 720 µm and grind it to a thickness of 150 µm or less. The coarse grinding typically removes approximately 90 percent of the excess material. A typical two step backgrinding operation will use dual spindles with grinding wheels mounted on each spindle.
