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.

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 configured to project a patterned radiation beam onto a target portion of a substrate held on a substrate holder in an indent on a substrate table, the apparatus includes a liquid supply system configured to at least partly fill a space between a projection system and the substrate with liquid; a barrier structure configured to substantially contain the liquid within the space; and a heat pipe supplied, in use, with a temperature conditioned fluid and configured to thermally condition the substrate and/or the substrate holder at locations where localized cooling is likely to occur.

摘要:
In a lithographic projection apparatus, a liquid supply system maintains liquid in a space between the projection system and the substrate. The liquid supply system may further include a de-mineralizing unit, a distillation unit, a de-hydrocarbonating unit, a UV radiation source, and/or a filter configured to purify the liquid. A gas content reduction device may be provided to reduce a gas content of the liquid. A chemical may be added to the liquid using an adding device to inhibit lifeform growth and components of the liquid supply system may be made of a material which is non-transparent to visible light such that growth of lifeforms may be reduced.
