LITHOGRAPHIC APPARATUS, AND DEVICE MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a system that reduces lithography errors caused by immersion liquid.SOLUTION: A lithographic apparatus comprises: an illumination system configured to adjust a radiation beam; a support body configured to support a pattern forming device capable of imparting a pattern to the radiation beam in a cross section of the radiation beam to form a pattern formed radiation beam; a substrate table configured to hold a substrate; a projection system configured to project the pattern formed radiation beam onto a target portion of the substrate; a liquid supply system configured to fill at least a part of space between a final element of the projection system and the substrate with liquid; a seal member arranged to substantially contain the liquid within the space between the final element of the projection system and the substrate; and elements to control and/or compensate for evaporation of the immersion liquid from the substrate.
