A die is the actual bare IC chip and is the final product of the fabrication process. It is the individual chip made following the singulation of a wafer. Dies typically undergo packaging before being sold to the customer as a final product.

Overview[edit]
The die is the final product of the fabrication process. A fully processed wafer will undergo singulation following probing. Depending on the application, the die may be shipped to an assembly/packaging plant where it will undergo further encapsulation, producing the final chip that ships to customers.
Known good die[edit]

A known good die (KGD) is a special type of bare die that underwent additional testing and screening post-singulation. KGD testing ensures the die meets the required specification prior to getting packaged. KGDs are especially important in multi-chip packages where multiple dies in a single package must function correctly to produce the required product.
Die size[edit]
- Main article: die size
Die size refers to the length and width of the die. Since the die size and shape determines the total number of dies that may be realized from a single wafer, the die size is a strong indicator of cost.
