  • Bearing device and exposure apparatus
    Patent number: 10423079
    Abstract: The present disclosure provides a bearing device. The bearing device includes a bearing platform, a lifting passage extending through the bearing platform, a lifting structure in the lifting passage and a light reflection compensating block between the lifting structure and an inner wall of the lifting passage. A difference between a reflectivity ratio of a top surface of the light reflection compensating block and a reflectivity ratio of a bearing surface of the bearing platform is less than or equal to a threshold value. A difference between the reflectivity ratio of the top surface of the light reflection compensating block and a reflectivity ratio of a top surface of the lifting structure is less than or equal to the threshold value. The present disclosure further provides an exposure apparatus including the bearing device.
