Die-per-Wafer Estimator

This tool computes how many rectangular dies can fit on a circular wafer. A tentative graphical wafer layout is offered.

This tool is designed to provide quick results and may be slightly optimistic.  Especially, the layout engine assumes central scribe line symmetry. Slightly different die counts may be obtained using other layout conventions. Similarly, only simplified wafer features are considered: one flat/notch is defined by its height, and all scribe lines are equal.
