The defect cell clustering method includes generating a sample defect map showing a defect cell distribution by cell positions of bad samples comprised of products each including one or more defect cells among products each partitioned into a plurality of cells, selecting at least some cell positions having one or more defect cells as clustering targets from the sample defect map, selecting one or more suspected bad equipments for each of cell positions included in the clustering targets using pass equipment information for the product, and grouping the clustering targets into one or more clusters according to position coherence between a first cell position and a second cell position included in one cluster, the cell position and the second cell position each having at least one suspected bad equipment."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Defect cell clustering method and apparatus thereof","description":"Provided are a method of clustering defects generated in bad samples shown on a defect map of bad samples including bad products, and an apparatus thereof.
