Patent number: 6975387Abstract: Before measuring a wavefront aberration of a projection optical system, an image formation position of an image of a pattern of a test reticle which is formed on a predetermined surface is detected by an AF sensor. Based on a result of this detection, the position of an incident surface of a wavefront aberration measurement unit is adjusted, and a position of an image of the pattern with respect to the incident surface is adjusted. After this adjustment, the image of the pattern formed through the projection optical system is detected by the wavefront aberration measurement unit, and a wavefront aberration detection section is used to obtain wavefront aberration information of the projection optical system based on a result of this detection.Type: GrantFiled: January 29, 2003Date of Patent: December 13, 2005Assignee: Nikon CorporationInventor: Yasushi Mizuno
