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…
WebMay 30, 2006 · Stacking of memory chips needs also thin silicon. For power devices it is reduction in electrical resistance. For smart-cards and related applications the main feature is the flexibility of thin silicon, which makes the IC-chip capable of surviving daily use. The question is: what are the mechanical properties after thinning and chip-singulation?
