  • Patent number: 8094287
    Abstract: A lithographic apparatus includes a projection system configured to project a patterned beam of radiation onto a target portion of a substrate. The projection system includes a first gas-conditioned sub-environment and a second gas-conditioned sub-environment. The apparatus includes a gas control unit configured to control the feeding of conditioned gas into the first sub-environment and into the second sub-environment via the first sub-environment so as to prevent contamination from the second sub-environment to the first sub-environment. The apparatus includes a gate configured to leak the conditioned gas at a rate from the second sub-environment to ambient atmosphere, and a detector configured to detect at least one property of the second gas-conditioned environment.
    Type: Grant
    Filed: September 25, 2008
    Date of Patent: January 10, 2012
    Assignees: ASML Netherlands B.V., Carl Zeiss SMT AG
    Inventors: Tjarko Adriaan Rudolf Van Empel, Erik Roelof Loopstra, Antonius Johannes Van Der Net, Yuri Johannes Gabriel Van De Vijver, Bernhard Gellrich, Bauke Jansen, Rens Sanderse

  • Patent number: 7446849
    Abstract: A lithographic apparatus is disclosed. The apparatus includes a projection system configured to project a patterned radiation beam onto a target portion of a substrate. The projection system includes a housing and a plurality of optical elements arranged in the housing. The apparatus also includes an inlet for feeding conditioned gas to the housing and a gas exhaust for exhausting the conditioned gas from the housing for providing a gas conditioned environment in the housing. At least one gate is provided for providing communication of the gas conditioned environment with ambient atmosphere. The gate is arranged to provide a predetermined leakage of the conditioned gas to the ambient atmosphere.
