Abstract

An electron beam defect classification system, that includes (a) an imager that is configured to generate an electron beam image of a region of a sample by illuminating the region with an electron beam; and (b) a processing circuit configured to process the electron beam image to provide a defect classification result. The processing circuit includes an artificial intelligence processor that is configured to apply artificial intelligence processing on the electron beam image to provide the defect classification result. The artificial intelligence processing represented an artificial intelligence process that exhibits an accuracy that is contributed to a training of the artificial intelligence process using a dataset that has undergone a label error reduction process.
