Abstract: A wafer map is classified using the machine learning based model and a signature on the wafer map. The machine learning based model uses transfer learning. The machine learning based model can be trained using images from various sources that are extracted and augmented and their features extracted. These extracted features can be classified into defects that occur during semiconductor manufacturing.
