Patent number: 10191107Abstract: Failure types that caused defective items to fail testing are identified, the defective items are grouped by the failure types to produce failure-type groups, and the defective items are analyzed to identify defect types that caused the failures. Failure-type limited yield within each of the failure-type groups, and failure-type group-specific defect ratio based on proportions of the defect types within each of the failure-type groups are determined. Additionally, each failure-type group-specific defect ratio is weighted using the failure-type limited yield to produce a weighted failure-type group-specific defect limited yield.
