The present invention provides a determination method of determining a light intensity distribution to be formed on a pupil plane of an illumination optical system in an exposure apparatus, the method including a step of setting a cut line used to evaluate an image of a pattern of a mask, which is formed on an image plane of a projection optical system, and a target value of a dimension of the image, and a step of obtaining the dimension of the image of the pattern on the cut line, and determining a weight to be applied to each of a plurality of element light sources such that the obtained dimension comes close to the target value of the dimension, thereby determining, as the light intensity distribution, light sources obtained by combining the plurality of element light sources applied with the weights. |
