Abstract:
PROBLEM TO BE SOLVED: To improve the effect of preventing the infiltration of contaminants into a projection system of a lithographic apparatus. SOLUTION: The lithographic apparatus has a projection system configured to project a patterned radiation beam onto a substrate. The projection system has an opening that allows the patterned radiation beam to pass therethrough. At least part of the opening has an inclined surface of a wall of the projection system and an inclined surface of a mirror of the projection system. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To suppress transmission of undesirable vibrations with respect to a lithography device and a device manufacturing method. SOLUTION: The lithography device includes a projection system configured to project an image on a substrate, a substrate table configured to support the substrate, a first chamber including the projection system, and a second chamber including the substrate table and first frame. The device includes a base frame configured so as 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 device includes a support coupled to the first frame. The support is configured to support the first chamber through coupled openings that the intermediate frame and second chamber have. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
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.
