Abstract:
An exposure apparatus comprising:a projection system having an exposure field that is decentered with respect to an optical axis in order to project a pattern formed on a mask onto a photosensitive substrate; an illumination optical system that forms an illumination field on the mask, the illumination field being decentered with respect to the optical axis of the projection system; a drive that relatively moves the mask and the photosensitive substrate along a scanning exposure direction with respect to the projection system; a first illumination adjustment mechanism that adjusts an illumination characteristic along the scanning exposure direction in one of: (a) the exposure field of the projection system, and (b) the illumination field formed on the mask; a second illumination adjustment mechanism that adjusts an illumination characteristic in a direction crossing the scanning exposure direction in one of: (a) the exposure field of the projection system, and (b) the illumination field formed on the mask; a first telecentricity adjustment mechanism that applies an oblique component to telecentricity in one of: (a) the exposure field of the projection system, and (b) the illumination field formed on the mask; and a second telecentricity adjustment mechanism that adjusts telecentricity changing in accordance with a position from the optical axis in one of: (a) the exposure field of the projection system, and (b) the illumination field formed on the mask.
