    • An exposure apparatus for exposing a substrate by emitting exposure light thereto through a projection optical system and liquid, has a detection apparatus that detects whether the liquid is present on an object disposed lower than a front end of the projection optical system. Another detection apparatus has an emitting portion that emits detection light to an immersion area between the projection optical system and an object disposed on an image plane side thereof, and a light-receiving portion disposed at a predetermined position for the detection light; therein, at least one of size and shape of the immersion area is obtained based on light receiving results. The detection apparatus is used to detect the presence of liquid on such lower-disposed object, the state of the immersion area, or shape or contact angle of the liquid. Optimal measures are taken, based on detection results, for maintaining high exposure and measurement accuracies.
    • 一种用于通过投影光学系统和液体向其发射曝光的曝光基板的曝光装置,具有检测装置,其检测液体是否存在于投影光学系统的前端下方的物体上。 另一种检测装置具有发射部分,其向投影光学系统和设置在其图像平面侧的物体之间的浸没区域发射检测光;以及光接收部分,设置在用于检测光的预定位置; 其中,基于光接收结果获得浸渍区域的尺寸和形状中的至少一个。 该检测装置用于检测这种下位物体上的液体的存在,浸渍区域的状态,或液体的形状或接触角。 基于检测结果,采取最佳措施,保持高曝光和测量精度。
