Abstract:
PURPOSE: An immersion lithography device and a manufacturing method thereof are provided to effectively and efficiently remove undesirable droplets from the surface of a substrate or a substrate table. CONSTITUTION: An immersion lithography device comprises the following: a projection system having an optical axis; a substrate table formed to maintain a substrate, defining the facing surface of the substrate and the substrate table itself; and a fluid handling structure for supplying an immersion liquid to an immersion space located on the surface facing the projection system. The fluid handling structure includes a fluid removal device(400), and a droplet removal device to remove droplets(200) form the immersion liquid.
Abstract:
PROBLEM TO BE SOLVED: To provide an improved apparatus for predicting force exerted to a substrate by immersion liquid and controlling canceling force such as disturbance force exerted by a positioner. SOLUTION: The immersion lithographic apparatus has a pressure sensor configured to measure the pressure of the immersion liquid in a space between the substrate and a projection system. A control system is responsive to a pressure signal generated by the pressure sensor and controls the positioner to exert force on a substrate table to compensate for the force exerted on the substrate table by the immersion liquid.

Abstract:
PROBLEM TO BE SOLVED: To provide a device capable of removing undesired droplets from a surface of a substrate and/or a substrate table more effectively and efficiently. SOLUTION: A fluid handling system for an immersion lithography apparatus has a fluid removal device to remove immersion liquid from an immersion space, and a droplet removal device to remove a droplet of immersion liquid, wherein: the droplet removal device is located further from an optical axis than the fluid removal device, and the droplet removal device includes a porous member which faces, e.g., the substrate being exposed and/or the substrate table.
