摘要:
A lithographic apparatus is provided that includes a substrate holder configured to hold a substrate, and a heat pipe to maintain the substrate holder at a substantially uniform temperature. The heat pipe has a chamber containing a liquid reservoir and a vapor space, and a heating element at least partly in contact with liquid in the chamber.
摘要:
A heat pipe to maintain an object at a substantially uniform temperature is disclosed. The heat pipe includes a chamber containing a liquid reservoir and a vapor space, part of the chamber being defined by a condensing surface, and a liquid transporter to apply a force additional to gravity to liquid to transport liquid away from the condensing surface towards the reservoir, wherein the condensing surface is shaped such that condensed liquid moves along it towards the liquid transporter.

摘要:
A lithographic apparatus is disclosed that includes a substrate table configured to support a substrate on a substrate supporting area and a heater and/or temperature sensor on a surface adjacent the substrate supporting area.
摘要:
Methods and apparatus for maintaining the thermal equilibrium of a substrate and an immersion lithographic apparatus are disclosed using or having a timetable comprising information regarding the position, speed and/or acceleration of the substrate; and an evaporation controller and/or condensation controller acting to decrease localized evaporation and/or increase localized condensation in response to the information in the timetable. Evaporation of liquid from the surface of the substrate cools it down, while condensing liquid on its bottom surface heats the substrate locally.
摘要:
A lithographic apparatus is described having a liquid supply system configured to at least partly fill a space between a projection system of the lithographic apparatus and a substrate with liquid, a barrier member arranged to substantially contain the liquid within the space, and a heater.
