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… WebJun 2, 2024 · Dicingis the process by which die are separated from a wafer of semiconductor following the processing of the wafer.
