摘要: In a method of inspecting a mask, an image of a pattern on the mask may be obtained. A histogram of the image by grey levels may be obtained. The histogram may be compared with information of the pattern to detect a defect of the mask. Thus, reliability of defect detection in the mask may be remarkably improved.
