Original Abstract Submitted

a defect detection device includes: a memory configured to store a layout image indicating a circuit pattern and indicating a dummy pattern; and a controller comprising an artificial neural network configured to learn the layout image, the controller being configured to: determine, based on an inspection image obtained by photographing an area including a defect on a wafer, whether the defect is in a first area in which the circuit pattern is positioned or in a second area in which the dummy pattern is positioned, by using the artificial neural network, and determine a type of the defect based on whether the defect is positioned is in the first area or in the second area.
