Publication number: 20190258040Abstract: Fluorescence is generated from an irradiated point on an inspection surface of a sample and the fluorescence is collected by an objective lens. Here, because of the magnification chromatic aberration of the objective lens, the fluorescence going out from the objective lens travels along a path shifted from the irradiation light and changed substantially into a non-scan light by a galvano-scanner. The fluorescence passes through a dichroic mirror into a plane-parallel plate after light of unnecessary wavelength is removed by a filter. The plane-parallel plate is driven in synchronization with the galvano-scanner by a computer and corrects the shift and inclination of the optical axis generated by the magnification chromatic aberration of the objective lens. Then, the fluorescence forms an image of the irradiation point of the inspection surface of the sample on a pin hole of a pin hole plate by using a collective lens.Type: ApplicationFiled: May 1, 2019Publication date: August 22, 2019Applicant: NIKON CORPORATIONInventors: Yuki YOSHIDA, Naoshi AIKAWA

Patent number: 7385165Abstract: A multibeam type scanning microscope that has N beams, wherein the system is devised so that the respective beams perform scanning in LM stages in the Y direction at maximum magnification where the discrete scanning direction is the Y direction, thus performing scanning in an area of N×LM stages overall, and scanning is controlled so that the following processes (1) and (2) are successively repeated LK times at a magnification that is 1/LK times the maximum magnification. Here, L, M and N are integers of 2 or greater, and K is a natural number. (1) The respective beams perform scanning in the Y direction at a sampling interval that is LK times that at the maximum magnification. (2) When scanning of LM-K stages is completed in the Y direction, and the repetition is less than the LKth time, the scanning skips ((N?1)×LM-K+1) stages.Type: GrantFiled: December 4, 2006Date of Patent: June 10, 2008Assignee: Nikon CorporationInventor: Naoshi Aikawa
