  • Publication number: 20110236809
    Abstract: A method for examining at least one wafer (13) with regard to a contamination limit, in which the contamination potential of the resist (13a) of the wafer (13), which resist (13a) outgasses contaminating substances, is examined with regard to a contamination limit before the wafer (13) is exposed in an EUV projection exposure system (1). The method preferably includes: arranging the wafer (13) and/or a test disc coated with the same resist (13a) as the resist (13a) of the wafer (13) in a vacuum chamber (19), evacuating the vacuum chamber (19), and measuring the contamination potential of the contaminating substances outgassed from the wafer (13) in the evacuated vacuum chamber (19), and also comparing the contamination potential of the wafer (13) with a contamination limit. An EUV projection exposure system (1) for carrying out the method is also disclosed.

  • Publication number: 20110227462
    Abstract: A household appliance includes a cabinet-shaped housing comprised of a plurality of walls. At least one of the walls has an arrangement of embossings. The arrangement of embossings includes a first embossing arranged centered in relation to a center of the at least one wall and configured in the shape of a ring when viewed from above. A second embossing is arranged outside the first embossing in substantial concentric relationship to the first embossing and configured in the shape of a ring when viewed from above. At least one third embossing is arranged outside the second embossing and has a strip-shaped configuration. The presence of embossings in the at least one wall is able to reduce vibrations and thereby significantly reduce the amount of unwanted noise.

  • Publication number: 20110058147
    Abstract: A cleaning module for an EUV lithography device with a supply (206) for molecular hydrogen, a heating filament (210) and a line (212) for atomic and/or molecular hydrogen. The line (212) has at least one bend with a bending angle of less than 120 degrees, and has a material on its inner surface which has a low recombination rate for atomic hydrogen. The supply (206) is of flared shape at its end, which faces the heating filament (210). A gentler cleaning of optical elements is achieved with such a cleaning module, or also by exciting a cleaning gas with a cold cathode or a plasma, or by filtering out charged particles via of electrical and/or magnetic fields.

  • Patent number: 7881828
    Abstract: A bus module for connecting electrically triggerable fluidic valves to a data bus. The bus module has an electrical circuit configuration, which evaluates address data and user data from data telegrams transmitted on the data bus and which triggers a fluidic valve determined by the address data in accordance with the user data of the data telegram. In order to keep the current load on the bus module low particularly when triggering hydraulic valves, the electronic circuit configuration, following the reception of user data in the form of a switch-on command for one of the fluidic valves connected to the bus module, first constantly supplies a supply voltage to the fluidic valve determined by the address data during a gate-controlled rise time of specifiable duration. Following the expiration of the gate-controlled rise time, the electronic circuit configuration supplies the fluidic valve with the supply voltage in a pulse width modulated form having a specifiable pulse control factor.
