    Wafer Thinning Techniques for Ultra-thin Wafers

    All commercially available grinding systems use a two-step process including a coarse grinding (with thinning rates of about 5 µm/sec) and a subsequent fine grinding (thinning rate ≤1µm/sec). The second step of the process is necessary to remove most of the damage layer created by the coarse grinding step and reduce surface roughness.
