Wafer backgrinding is a semiconductor device fabrication step during which wafer thickness is reduced to allow stacking and high-density packaging of integrated circuits (IC). ICs are produced on semiconductor wafers that undergo a multitude of processing steps. The silicon wafers predominantly used today have diameters of 200 and 300 mm. They are roughly 750 μm thick to ensure a minimum of mechanical stability and to avoid warping during high-tem… WebThese die backside defects include micro-cracks and chip-outs caused by back-grinding and wafer saw. Backside micro-cracks caused by ejection needles used for ejecting die from the wafer tape during the die attach process have also been known to cause cracks.
