Wafer Backgrinding | Silicon Wafer Thinning | Wafer Backgrind
The back grinding 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 …
Wafer 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.
