    摘要： An illumination optical system for, when installed in an exposure system, realizing a suitable illumination condition by varying the polarized state of the illumination light according to the pattern characteristics of the mask while suppressing the loss of the intensity of the light. The illumination optical system has a light source unit for supplying a linearly polarized light for illuminating surfaces to be illuminated therewith, and a polarized state changing device for changing the polarized state of the illuminating light from a predetermined polarized state to a nonpolarized state and vice versa. The polarized state changing device is arranged in the optical path between the light source unit and the surfaces to be illuminated. The polarized state changing device can be removed from the illumination optical path and has a depolarizer for selectively depolarizing the incident linearly polarized light.

    摘要： An illumination optical system illuminates an irradiated surface with light supplied from a light source. The illumination optical system includes a diffractive optical element disposed in an optical path of linearly polarized light supplied from the light source. The diffractive optical element forms a multipole illumination field including a plurality of illumination fields. The illumination optical system also includes an optical integrator that forms a multipole light source including a plurality of planar light sources with light that has passed through the multipole illumination field. The illumination optical system also includes a polarization optical member disposed in an illumination optical path and that sets a polarization direction of light that has passed through the multipole light source to a predetermined polarization direction.
