WebWafer sort or chip probe data can be collected from both electrical probe and automatic test equipment (ATE). The inline or end-of-line (EOL) data can be correlated to perform yield correlation using defectivity analysis equipment. It enables high-yield/low-yield analysis to identify yield problems. WebOne simple yield model assumes a uniform density of randomly occurring point defects as the cause of yield loss. If the wafer has a large number of chips (N) and a large number of randomly distributed defects (n), then the probability Pk that a given chip contains k defects may be approximated by Poisson's distribution, or Pk = e-m (m k /k!) where m = n/N.
