INSPECTION METHOD AND INSPECTION APPARATUS
A high resolution optical image is acquired by irradiating a mask with light emitted by a light source via a high resolution optical system. A low resolution optical image is acquired by irradiating the same mask with the light via a low resolution optical system. The design data of the mask pattern...

| description | A high resolution optical image is acquired by irradiating a mask with light emitted by a light source via a high resolution optical system. A low resolution optical image is acquired by irradiating the same mask with the light via a low resolution optical system. The design data of the mask pattern is corrected in light of shapes and dimensions determined according to at least one of a manufacturing process of the mask and a manufacturing process of a semiconductor device to be manufactured by transferring the mask pattern to a semiconductor wafer. Reference image data are generated corresponding to the high resolution optical image and the low resolution optical image. Whether the defect detected in the high resolution optical image is true or false is determined according to information of the defect detected in the low resolution optical image. |
