Abstract:
An exposure method for exposing a rectangular substrate to a pattern of a mask by transferring a mask stage carrying a mask formed with the pattern and a rectangular substrate holder carrying the substrate in a first direction, the method comprising the steps of:placing the substrate whose longer sides are longer than the shorter sides of the substrate holder, on the substrate holder such that the longer sides of the substrate are generally arranged along the shorter sides of the substrate holder; exposing a first area of the substrate to the pattern of the mask by transferring the mask stage and the substrate holder in the first direction; transferring the substrate holder in a second direction which is generally perpendicular to the first direction; and exposing a second area of the substrate, which is adjacent to the first area along the second direction, by transferring the mask stage and the substrate holder in the first direction.
