A grinding wheel is a wheel composed of an abrasive compound and used for various grinding (abrasive cutting) and abrasive machining operations. Such wheels are used in grinding machines.. The wheels are generally made from a composite material consisting of coarseparticle aggregate pressed and bonded together by a cementing matrix (called the bond in grinding wheel terminology) to form a ...
Wafer backgrinding is a semiconductor device fabrication step during which wafer thickness is reduced to allow stacking and highdensity 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 .
