Abstract: A method for detecting a defect of a substrate having a semiconductor device is provided to shorten an interval of inspection time by performing an inspection process while scanning the same substrate only in a first direction. A first inspection region where patterns are repeated in a first direction and a second inspection region where patterns are repeated in a second direction are set in a substrate having a semiconductor device. A first basic inspection size is specified in the first inspection region wherein the first basic inspection size becomes a comparison unit in an inspection process and is repeated in the first direction. A second basic inspection size is specified in the second inspection region wherein the second basic inspection size becomes a comparison unit in an inspection process and is repeated in the second direction. While a member for acquiring an image confronts the upper surface of the substrate, the substrate is transferred in the first direction to obtain the image of the upper portion of the semiconductor device in the first and second inspection regions. The images of the first inspection region corresponding to the first basic inspection size are compared to detect a defect of the first inspection region. The images of the second inspection image corresponding to the second basic inspection size are compared to detect a defect of the second inspection region. The first inspection region can include a partial cell region and a sense amplification region(206).

Abstract: A method for inspecting a wafer is provided to discriminate defect from noise and to detect the defect by using a gray level signal value of a determination difference image. A normal pattern image of a unit inspection region and a pattern image to be inspected are multi-scanned with different inspection conditions(S210). The normal pattern image and the pattern image to be inspected are compared with each other by using same inspection conditions to store differences as difference images(S230). Gray level signal values of the stored difference images are calculated to generate a determination difference image(S240,S250). Defect and noise are determined by calculating a gray level signal value of the determination difference image(S270).
