Silicon Wafer Backgrinding Process

Silicon Wafer Backgrinding Process. 2 partial wafer grinding is an efficient grinding method to process broken or damaged wafers, or wafer sections.This technique can be employed to process wafers that had been damaged, or wafer sections that are still intact, thereby avoiding loss of the entire waferWafer backgrinding - Wikipedia,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-temperature processing steps. Wafer Backgrinding Services | Silicon Wafer Thinning Services,The backgrinding process involves using a diamond-resin bonded grinding wheel to remove the silicon material from the back of a silicon wafer. Using a grinding wheel is highly effective, and faster and less expensive than chemical-mechanical processes and is used to remove the bulk of substrate material prior to final finish grind, polish or chemical etch.
