Abstract:
PROBLEM TO BE SOLVED: To provide a lithographic apparatus, in which a liquid supply system maintains a liquid in a space between a final element of a projection system and a substrate with a liquid confinement system. SOLUTION: A liquid supply system 180 further comprises a de-mineralizing unit 130, a distillation unit 120 and a UV radiating source 145 for the purification of an immersion liquid. Chemicals can be added to the immersion liquid for the inhibition of organism 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 organisms is reduced.

PROBLEM TO BE SOLVED: To provide lithographic equipment in which a liquid supply system keeps liquid in a space between the final component of the projection system and a substrate by a liquid sealing system. SOLUTION: The liquid supply system 100 is further equipped with a de-mineralizing unit 130, a distillation unit 120, and a UV radiation source 145 to purify an immersion liquid. Chemicals can be added to the immersion liquid to inhibit the growth of living organisms. The components of the liquid supply system 100 can be made of materials non-transparent to visible light to prevent the growth of living organism. COPYRIGHT: (C)2009,JPO&INPIT

Abstract:
In a lithographic projection apparatus a liquid supply system maintains liquid in a space between a final element of the projection system and the substrate with a liquid confinement system. The liquid supply system further comprises a de-mineralizing unit, a distillation unit and a UV radiating source for the purification of immersion liquid. Chemicals may be added to the immersion liquid for the inhibition of 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 is reduced.
