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. WebStricter requirements in the wafer manufacturing process have made edge measurements important for both 200 mm and 300 mm wafers. In fact, the SEMI standard for 300 mm wafers specifically requires a “polished edge.” Polishing the edge is done in order to reduce wafer cracking and chipping under stress during transport or thermal processing.
