摘要
The present paper introduces a novel yield impact quantification method which is designed especially to have robustness to clustered defects and false detection by inspection tools. The yield impact can be obtained by non-defective area analysis of cumulative defect maps. The accuracy of the proposed method is discussed based on experimental results that were obtained using actual in-line inspection data. Application of the proposed method is contributing to rapid yield ramp-up.
