Patent ID: 6937754

Claim:
An inspection equipment comprising: means for supporting a specimen and moving the specimen to a predetermined position of inspection; means for projecting an ultraviolet light through an ultraviolet objective lens onto the specimen supported on the specimen supporting means; an ultraviolet imaging means for detecting a reflected or transmitted light from the specimen illuminated by the ultraviolet light projecting means to pick up an image of the specimen; means for projecting a visible light to the specimen supported on the specimen supporting means; visible light imaging means for detecting a reflected or transmitted light from the specimen illustrated by the visible light projecting means to pick up an image of the specimen; means for processing the images picked up by the ultraviolet imaging means and the visible light imaging means selectively in response to the defect size of the specimen; and means for automatically selecting between the images picked up by ultraviolet imaging means and the visible light imaging means in response to the defect size of the specimen, the wavelength of the ultraviolet light emitted by the means for projecting an ultraviolet light, and the numerical aperture of the ultraviolet objective lens.
