  • Patent number: 8815039
    Abstract: A next processing pin is applied as a follow-on pin to a stone, wherein the stone is held by a preceding pin and fixed to the stone by way of a first adhesive bonding location. The preceding pin is separated from the stone. The follow-on pin is fixed to the stone by way of a second adhesive bonding location spaced from the first adhesive bonding location. The follow-on pin frontally receives a fluid adhesive at a spacing from the stone and the spacing between the adhesive-coated front end and the stone is reduced until the adhesive front end contacts the stone. The adhesive is hardened at the contact location as the second adhesive bonding location and heat is transferred by way of the preceding pin to the first adhesive bonding location A force component is exerted on the preceding pin to release the pin from the stone and to hold the stone with the next pin.

  • Patent number: 8503958
    Abstract: A signal processor for processing a receiving signal having a first usable frequency band and a second usable frequency band includes a first mixer for mixing the receiving signal with a first local oscillator signal, wherein a frequency of the first local oscillator signal is asymmetrical between the first usable frequency band and the second usable frequency band. The first mixer is implemented to obtain an in-phase signal and a quadrature signal, having a first signal portion representing a mixed image of the first usable frequency band, and having a second signal portion representing a mixed image of the second usable frequency band. The signal processor comprises a second mixer) for mixing the in-phase signal and the quadrature signal by using the second local oscillator signal.

  • Publication number: 20120086925
    Abstract: A method for preventing contaminating gaseous substances (18) from passing through an opening (17b) in a housing (4a) of an EUV lithography apparatus (1), wherein at least one optical element for guiding EUV radiation (6) is arranged in the housing (4a). The method involves: generating at least one gas flow (21a, 21b) which deflects the contaminating substances (18, 18?), and in particular is directed counter to the flow direction (Z) thereof, in the region of the opening (17b). The gas flow (21a, 21b) and the EUV radiation (6) are generated in pulsed fashion and the pulse rate of the gas flow (21a, 21b) is defined in a manner dependent on the pulse rate of the contaminating substances (18, 18?) released under the action of the pulsed EUV radiation (6), wherein both pulse rates are preferably equal in magnitude, and wherein, in the region of the opening (17b), the gas pulses temporally overlap the pulses of the contaminating substances (18, 18?).

  • 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.
