WebFor instance, if we sampled 800 units and found 50 defects with 5 opportunities per unit and multiplied this figure by 1 million, the DPMO would be as follows: 50 / (800 × 5) × 1000000 = 12500. Yield: The percentage of a process that is free of defects. To calculate process yield, we use the following formula: Yield (%) = (1 − DPO) × 100 WebDefects, or defect density, is ill-defined, and in turn needs to be inferred from the average number of faults. This paper discusses the relation between defects, faults and semiconductor yield, and attempts to illuminate areas that invite closer attention.
