Patent ID: 7327449

Claim:
An inspection method for an exposure apparatus for projecting a surface of a secondary light source of an illumination optical system onto a substrate through a projection optical system, the inspection method comprising: preparing an inspection photosensitive substrate as the substrate; illuminating a first region which does not include a pupil end of the projection optical system and illuminating a second region which includes the pupil end of the projection optical system and which is not overlapped with the first region before the illuminating the first region or after the illuminating the first region, in a state in which a surface of the photosensitive substrate and the surface of the secondary light source of the illumination optical system are optically conjugate with each other; inspecting an illumination axis offset of the exposure apparatus based on a pattern obtained by developing the photosensitive substrate; and wherein the state in which the surface of the photosensitive substrate and the surface of the secondary light source of the illumination optical system are optically conjugate with each other is formed by providing a pattern member comprising a pattern formed on a surface between the illumination optical system and the projection optical system or between the projection optical system and the photosensitive substrate.
