Patent ID: 8811714

Claim:
A determination method of determining a light intensity distribution to be formed on a pupil plane of an illumination optical system which illuminates a mask in an exposure apparatus including the illumination optical system and a projection optical system which projects a pattern of the mask onto a substrate, the method, performing the following steps by a computer, comprising: a first step of setting the pattern of the mask; a second step of setting a cutline used to evaluate an image of the pattern of the mask, which is formed on an image plane of the projection optical system, and a target position of the image; a third step of setting a plurality of element light sources which form the light intensity distribution of the illumination optical system; a fourth step of calculating an image of the pattern of the mask, which is formed on the cutline upon illuminating the pattern of the mask, for each of the plurality of element light sources; and a fifth step of determining an intensity of the element light source such that a position of the image of the pattern of the mask on the cutline from the calculated image comes close to the target position, thereby determining the light intensity distribution.
