Patent ID: 7457453

Claim:
A pattern inspection apparatus comprising: an image acquiring part for acquiring an image of an object substrate: an image processing part for processing the image acquired by the image acquiring part to detect defect candidates on the object substrate and to classify the detected defect candidate; a display having a screen on which a distribution of the detected defect candidates is displayed in a map form; an input device for inputting information of a non-inspection defect candidate to be masked on the object substrate; a memory part for storing data of the non-inspection defect candidate to be masked on the object substrate inputted on the screen by the input device; a mask region setting part for setting a region to be masked on the object substrate by using information on classified defect candidate from the image processing part and the non-inspection defect candidate from the input device; and an output part for output information of the defect detected on the object substrate by the image processing part other than the masked region set by the mask region selling part.
