Abstract (in Japanese) (See Japanese page) 
(in English) In lithography, which is one of the LSI fabrication processes, a layout pattern with a high failure probability is called a hotspot. In machine-learning based hotspot detection methods, Density Based Layout Feature, which considers only the area of wires in each local region, is widely used. Meanwhile, as we can see from the fact that the distance between wires is checked in design rule checking, when it is smaller, the transferred patterns of wires tend to form short circuits with a higher probability. Thus, the distance between wires is possibly an important measure for hotspot detection. Therefore, in this study, we propose and evaluate a hotspot detection method that considers the distance between wires as a feature vector.
