    Abstract: PROBLEM TO BE SOLVED: To provide a method of highly precisely adjusting a measuring optical system of a lithographic apparatus. SOLUTION: In the lithographic apparatus, a substrate table constituted to hold a substrate is movable to transfer the substrate between a substrate measuring position and a substrate processing position. The lithographic apparatus also includes a measuring system constituted to measure at least one aspect or a characteristic of the substrate when the substrate table holds the substrate in the measuring position. The measuring system is constituted to guide at least one measuring beam and/or a field toward the front surface of the substrate. A projection system is constituted to project a patterned radiation beam onto the target of the substrate when the substrate table holds the substrate in the substrate processing position. An adjusting system is constituted to supply adjusting fluid to at least a part of the path of the measuring beam and/or the field of the measuring system to adjust the part of the path.

    Abstract: PROBLEM TO BE SOLVED: To provide a level sensor capable of executing improved position measurement correction to find a height of a substrate.
    SOLUTION: The level sensor generates one or a plurality of measuring beam(s), and emits the measuring beam(s) toward a measuring spot on the substrate to generate a reflected measuring beam(s). The level sensor generates also one or a plurality of reference beam(s). A detector detects respectively both the reflected measuring beam (s) and the reference beam(s), and generates respectively a measuring signal indicating the height in the measuring spot, and a reference signal. A processor receives the signals, and corrects the measuring signal, based on the reference signal. The level sensor has optical constitution in a prescribed area near to a place to arrange the substrate. The measuring beam(s) and the reference beam(s) are propagated along substantially equal propagation optical paths within the prescribed area. The optical constitution deflects the reference beam(s) from the substantially equal propagation optical paths within the prescribed area to make at least one the reference beam not hit the substrate.

    解决方案:液位传感器产生一个或多个测量光束,并将测量光束朝向衬底上的测量点发射以产生反射的测量光束。 液位传感器还产生一个或多个参考光束。 检测器分别检测反射的测量光束和参考光束,分别产生指示测量点的高度的测量信号和参考信号。 处理器接收信号,并根据参考信号校正测量信号。 液位传感器在靠近用于布置基板的位置的规定区域中具有光学构造。 测量光束和参考光束在规定区域内沿着基本相等的传播光路传播。 光学构造将参考光束从规定区域内的基本上相等的传播光路偏转,使至少一个参考光束不会撞击到衬底上。 版权所有(C)2007,JPO&INPIT
