Abstract:
PURPOSE: A substrate table, an immersion lithography apparatus, and a method for manufacturing a device are provided to reduce the generation of defects on images by minimizing bubbles in the immersion lithography apparatus. CONSTITUTION: A pre-set size substrate(W) is contained in a recess(20). The recess includes a supporting region supporting the lower surface of the substrate and an edge. The edge is adjacently arranged to the edge of the substrate. A fluid draining system drains fluid from a gap(26) between the edges of the substrate and the recess. The fluid draining system includes a first duct(32) and a second duct(42) which are open toward the inside gap.
Abstract:
PROBLEM TO BE SOLVED: To reduce a possibility or an influence of bubbling in an immersion lithographic apparatus. SOLUTION: A substrate table for an immersion lithographic apparatus has a recessed portion constituted to store a substrate of given size, and a fluid extraction system configured to extract a fluid from a gap between an edge of the substrate and an edge of the recessed portion, wherein the fluid extraction system is characterized in that the flow rate of the fluid extracted from a local part of the gap is larger than the flow rate of the fluid extracted from other parts of the gap.
