发明名称 OPTICAL CHARACTERISTIC MEASURING DEVICE, OPTICAL CHARACTERISTIC MEASURING METHOD, EXPOSURE DEVICE, EXPOSURE METHOD, AND DEVICE MANUFACTURING METHOD
摘要 <p>An optical property measurement apparatus (90) is equipped with an optical system unit (93) that selectively places an opening section (97) for passing illumination light, a microlens array (98) for measuring wavefront aberration, and a polarization detection system (99) for measuring a polarization state of the illumination light on an optical path of the illumination light. Accordingly an illumination shape and a size of an illumination optical system, wavefront aberration of a projection optical system and a polarization state of the illumination light can be measured together. Therefore, for example, even when exposure is performed with polarized illumination that is a type of modified illumination, highly-accurate exposure can be achieved by adjusting various optical systems based on the measurement results.</p>
