发明名称 EXPOSURE APPARATUS AND DEVICE MANUFACTURING METHOD
摘要 An exposure apparatus comprises an original stage which holds an original, a substrate stage which holds a substrate, and a control unit which controls a measurement process of measuring a relative position between the original and substrate stages, wherein original-side measurement marks including an original-side rough-measurement mark and an original-side fine-measurement mark are formed on the original stage, substrate-side measurement marks including a substrate-side rough-measurement mark and a substrate-side fine-measurement mark are formed on the substrate stage, and the control unit controls the measurement process to perform rough measurement of the relative position between the original and substrate stages using the original-side and the substrate-side rough-measurement marks, correct the relative position between the original and substrate stages based on the result of the rough measurement, and then perform fine measurement of the relative position between the original and substrate stages using the original-side and substrate-side fine-measurement marks.
