Latest Patents

Qian Xu holds a patent titled "Ranking defects with yield impacts." This patent focuses on identifying failure types that cause defective items to fail testing. The process involves grouping defective items by their failure types to produce failure-type groups. These groups are then analyzed to identify defect types responsible for the failures. The patent outlines a method for determining failure-type limited yield within each group and calculating a failure-type group-specific defect ratio based on the proportions of defect types. Additionally, it describes a process for weighting these ratios to produce a weighted failure-type group-specific defect limited yield. The final outcome is a ranking of defect types based on their influence on the total limited yield.
