<P>PROBLEM TO BE SOLVED: To reduce or eliminate risks of a defocusing error. <P>SOLUTION: An immersion lithographic apparatus is disclosed having a projection system configured to direct a patterned beam of radiation onto a substrate and a liquid handling system configured to supply and confine immersion liquid to a space defined between the projection system and a substrate, or a substrate table, or both. A controller is provided to adjust an angle of a lower surface of the liquid handling system relative to the top surface of the substrate during moving of the substrate and/or substrate table relative to the liquid handling system dependent upon a position of the substrate and/or substrate table relative to the liquid handling system and/or a direction of relative movement between the substrate and/or substrate table and the liquid handling system. <P>COPYRIGHT: (C)2012,JPO&INPIT |
