Sony Die simulation ps4

Die singulation, also called wafer dicing, is the process in semiconductor device fabrication by which dies are separated from a finished wafer of semiconductor.[1] It can involve scribing and breaking, mechanical sawing (normally with a machine called a dicing saw)[2] or laser cutting. All methods are typically automated to ensure precision and accuracy.[3] Following the dicing process the individual silicon chips may be encapsulated into chip carriers which are then suitable for use in building electronic devices such as computers, etc.

During dicing, wafers are typically mounted on dicing tape which has a sticky backing that holds the wafer on a thin sheet metal frame. Dicing tape has different properties depending on the dicing application. UV curable tapes are used for smaller sizes and non-UV dicing tape for larger die sizes. Dicing saws may use a dicing blade with diamond particles, rotating at 30,000 RPM and cooled with deionized water. Once a wafer has been diced, the pieces left on the dicing tape are referred to as die, dice or dies. Each will be packaged in a suitable package or placed directly on a printed circuit board substrate as a "bare die". The areas that have been cut or sawn away, called die streets, are typically
