Abstract:
PROBLEM TO BE SOLVED: To reduce effect of thermal expansion and thermal contraction in a liquid-immersion system using a supply system for supplying an immersion liquid to a substrate and/or a local area of a substrate table. SOLUTION: The lithographic apparatus includes a heater 400 and/or a temperature sensor 500 on a surface. The surface is a surface of at least one selected from the substrate table structured to support the substrate on a substrate support area, a liquid handling system, a projection system, a surface of a lattice of a positional measurement device or a sensor, and/or an exchange bridge. A nodal plate 600 is further included so as to support the substrate. The surface, on which the heater and/or temperature sensor are formed, is a surface of the nodal plate.

Abstract:
PROBLEM TO BE SOLVED: To reduce effect of thermal expansion and thermal contraction in a liquid-immersion system using a supply system for supplying an immersion liquid to a substrate and/or a local area of a substrate table. SOLUTION: The lithographic apparatus includes a substrate table configured to support the substrate on a substrate supporting area and including a plurality of heaters 400 and/or temperature sensors 500 arranged adjacently to a center part of the substrate supporting area. The plurality of heaters and/or sensors are elongated in a parallel direction substantially, and extend over the substrate support area from one edge end part to an opposite edge end part. A time when they are under a projection system during a period of imaging becomes shorter than a case where an elongated direction of the heaters and/or sensors are perpendicularly oriented to a first direction.

Abstract:
PROBLEM TO BE SOLVED: To improve compensation of cooling of a substrate due to evaporation of immersion liquid.SOLUTION: A substrate table assembly, an immersion lithographic apparatus and a device manufacturing method are disclosed. The substrate table assembly includes a substrate table to support a substrate; and a gas handling system to provide a gas to a region between the substrate table and a substrate mounted on the substrate table. The gas provided by the gas handling system has a thermal conductivity greater than or equal to 100 mW/(m K) at 298 K.
Abstract:
PROBLEM TO BE SOLVED: To provide a lithographic process where a process error caused by one or more heat sources can be reduced or minimized. SOLUTION: An immersion lithographic apparatus is provided. The immersion lithographic apparatus has a substrate table including a drain so configured as to receive an immersion liquid leaking into a gap between the edge of a substrate on the substrate table and the edge of a concave portion where the substrate is disposed. By directing one or more jets of the liquid toward the back side of a portion that supports the substrate, at least a portion of the concave portion that supports the substrate is thermally adjusted, thus providing a thermal adjustment system in the immersion lithographic apparatus.
