In integrated circuit (IC) manufacturing, a wafer''s defects tend to cluster. As the wafer size increases, the clustering phenomenon of the defects becomes increasingly apparent.When the conventional Poisson yield model is used, the clustered defects frequently cause false results. In this study, we propose a neural network-based modified Poisson yield model to predict the wafer yield in IC manufacturing. The proposed approach can reduce the phenomenon of the false predictions caused by the clustered defects. A case study is also presented, demonstrating the effectiveness of the proposed approach.Keywords: integrated circuit, defects, cluster, yield model, neural network
