| − | == Overview ==
| |
| − | The '''die''' is the final product of the [[fabrication process]]. A fully processed wafer will undergo [[singulation]] following [[wafer probing|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.

| |
| − | 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 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.
