WebFeb 8, 2024 · Taking place at the end of the semiconductor process flow, dicing is the process where the silicon wafer is finally turned into individual chips, or die, traditionally by means of a saw or laser. A saw blade, or laser, is used to cut the wafer along the areas between the chips called dicing lanes. 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) or laser cutting. All methods are typically automated to ensure precision and accuracy. Following the dicing process the individual silicon chips may be encapsulated into chip carriers which are the… WebThe cavity 1412 is positioned close to a chip singulation trench 1420 so that only the lamella 1411 separates the cavity 1412 from the chip singulation trench 1420.
