Publication number: 20070009148Abstract: The present invention provides a method, an optical inspection apparatus as well as a computer program product for optical inspection of a surface. The optical inspection apparatus can be effectively applied for optical inspection of periodic structures on e.g. a semi-conductor wafer for the purpose of quality control. By effectively splitting a light beam into a plurality of spatially separated light beams and by selective usage of these light beams, various surface segments of the surface can be inspected simultaneously by superposition of respective images. A resulting superposition image can then be compared with a reference image for detection of defects of the surface.Type: ApplicationFiled: July 6, 2005Publication date: January 11, 2007Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Gernot Brasen, Christian Laue, Matthias Loeffler, Heiko Theuer
