摘要:
A lithographic apparatus includes a projection system configured to project an image onto a substrate, a substrate table configured to support the substrate, a first chamber that at least partially surrounds the projection system, and a second chamber that at least partially surrounds the substrate table and a first frame. The apparatus includes a base frame configured to support the second chamber, and an intermediate frame coupled to the base frame. The intermediate frame is configured to separate the first chamber and the second chamber. The apparatus includes a support coupled to the first frame. The support is configured to support the first chamber through a coupled opening in the intermediate frame and the second chamber.

A lithographic apparatus includes a projection system configured to project a patterned beam of radiation onto a substrate. The projection system being provided with an opening through which the patterned beam of radiation may pass. At least part of the opening comprises a sloped surface of a wall of the projection system and a sloped surface of a mirror of the projection system.

摘要:
The invention relates to a method for determining a suppression factor of a suppression system. The suppression system is arranged to suppress migration of a contaminant gas out of a first system. The suppression factor is an indication of the performance of the suppression system. The method includes introducing a tracer gas in the sub-system, providing a detection system configured to detect the amount of tracer gas that has migrated out of the first system, determining a first suppression factor for the suppression system for the tracer gas. The method further includes determining a second suppression factor for the suppression system for the contaminant gas based on the first suppression factor.
