Silicon Wafer Crusher Specifications
Fast and precise surface measurement of backgrinding ...
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. The roughness of the surface should be often in the range of Ra <10 nm ...
