About the Semiconductor Yield Calculator
This educational model relates a uniform defect-density assumption to die area.
Formula
After converting area to cm², yield equals e raised to negative defect density times area.
Example
A 1 cm² die at 0.5 defects/cm² gives about 60.65% Poisson yield.
Notes
Real yield depends on process, defect distribution, redundancy, testing, binning and maturity.
