  • Publication number: 20080128636
    Abstract: A gas analyzing system is disclosed, the system including a gas analyzer and a reduced pressure chamber in which interior the gas analyzer is arranged, the reduced pressure chamber having an inlet configuration for a gas mixture inflow and an outlet configuration for a gas mixture outflow, wherein the outlet configuration during operation is connected to a pump system to facilitate the gas mixture outflow, the outlet configuration having a channel section and a flow section, the flow section having a cross-sectional area that is smaller than the cross-sectional area of the channel section.

  • Patent number: 7115886
    Abstract: In-situ cleaning of optical components for use in a lithographic projection apparatus can be carried out by irradiating a space within the apparatus containing the optical component with UV or EUV radiation having a wavelength of less than 250 nm, in the presence of molecular oxygen. Generally, the space will be purged with an ozoneless purge gas which contains a small amount of molecular oxygen in addition to the usual purge gas composition. The technique can also be used in an evacuated space by introducing a low pressure of molecular oxygen into the space.

  • Patent number: 6862075
    Abstract: Contaminant particles travelling with a projection beam in a lithographic projection apparatus are ionized. A purge gas may be attracted towards getter plates provided upstream of the purge gas supply. A magnetic field traps electrons generated by the ionizer to improve the ionization of the purge gas. The contaminant particles can be ionized by generating a plasma in a tube having a greater length than width.

  • Patent number: 6828569
    Abstract: Cleaning of optical components for use in a lithographic projection apparatus can be carried out by irradiating a space within the apparatus containing the optical component with UV or EUV radiation having a wavelength of less than 250 nm, in the presence of an oxygen-containing species selected from water, nitrogen oxide and oxygen-containing hydrocarbons. Generally, the space will be purged with an ozone-less purge gas which contains a small amount of the oxygen-containing species in addition to the usual purge gas composition. The technique can also be used in an evacuated space by introducing a low pressure of the oxygen-containing species into the space.
