Mixed-type wafer failure pattern recognition
Web1 apr. 2024 · The defect pattern on a wafer map allows process engineers to detect the operation or facility abnormalities early and provide quick feedback. Wafer maps with similar defect patterns tend to have the same problem in the manufacturing process (Hansen, Nair, & Friedman, 1997). Web1 jul. 2024 · In semiconductor manufacturing, pattern analysis of wafer maps is important in terms of failure analysis and activities to increase yield. Image classification research …
