Die CuttingDuring the die cutting or dicing process, a wafer with sometimes thousands of identical integrated circuits is cut into individual pieces, called dies. In between the functional parts of the circuits, a thin non-functional spacing is foreseen where a saw can safely cut the wafer without damaging the circuit. This spacing is called the scribe. The width of the scribe is very small, typically around 100 μm. A very thin and accurate saw is therefore needed to cut the wafer into pieces. Usually the dicing is performed with a water-cooled circular saw with diamond tipped blades.
