  • Fast and precise surface measurement of back-grinding

    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 μm in order to minimize subsurface damage and stress.
