Semiconductor Defect Classification
detect not only the location of a defect but also the type of defect as some of the product may still be commercially viable. The goal of this research is to use images of a single chip on the wafer, known as die images, to detect and classify defects. An example of a wafer bin map and a die image is presented in Figure 1. Figure 1.
