WebWafer dicing. In the context of manufacturing integrated circuits, wafer dicing is the process by which die are separated from a wafer of semiconductor following the processing of the wafer. The dicing process can involve scribing and breaking, mechanical sawing (normally with a machine called a dicing saw) [1] or laser cutting. WebBonded wafer grinding or ultra-thin grinding may cause edge chipping which is one of the critical issues leading to wafer breakage. Chipping may be induced by the rounded profile of the wafer's outer edges. The edge trimming process eliminates the rounded profile of the outer edge ensuring edge strength and chipping decrease. WebFront-side chipping becomes a yield concern when chips approach the active area of the die. Front-side chipping is predominantly dependent on blade grit, coolant flow and feed rate. Back-side chipping (BSC) occurs on the bottom surface of the wafer, as micro-cracks propagate away from the bottom of the cut and join together into chip out. c-spine herniated disc
