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. 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.

Wafer testing is a step performed during semiconductor device fabrication after BEOL process is finished. During this step, performed before a wafer is sent to die preparation, all individual integrated circuits that are present on the wafer are tested for functional defects by applying special test patterns to them. The wafer testing is performed by a piece of test equipment called a wafer prober. The process of wafer testing can be referred to in several ways: Wafer Final Test … WebA good starting point is 5, 10 and 15 minutes at High “H” setting with 30 seconds “on” and 30 seconds “off” cycle.
