Investigation of the influence and characterization for silicon wafer dicing process

Silicon wafers have been widely used as substrate materials in the semiconductor industry and micro electro-mechanical systems (MEMS).Silicon wafers are singulated into individual chips after device processing and before packaging.The street width of the component structures must to be kept at a minimum, which keeping the wafer surface available for integrated circuits or MEMS devices.The standard way to dice a semiconductor wafer is blade cutting.So the important thing is to minimize edge chipping and reduce the dicing blade width.Furthermore, the dicing process may induce subsurface damages and micro-cracks.important thing is to minimize edge chipping and reduce the dicing blade width.
