摘要:
A visual inspection apparatus and method using the scanning electron microscope are disclosed. An electron beam is scanned repeatedly on a sample, and an inspection and a reference image are generated by the secondary electrons generated from the sample or reflected electrons. From the differential image between the inspection image and the reference image, a defect is determined. The number of pixels in the generated image along the direction of repetitive scanning by the electron beam can be changed.
