  • Patent number: 7528395
    Abstract: A radiation source comprises an anode and a cathode that are configured and arranged to create a discharge in a gas or vapor in a space between anode and cathode and to form a plasma pinch so as to generate electromagnetic radiation. The gas or vapor may comprise xenon, indium, lithium and/or tin. The radiation source may comprise a plurality of discharge elements, each of which is only used for short intervals, after which another discharge element is selected. The radiation source may also comprise a triggering device, which device can facilitate improving the exact timing of the pinch formation and thus the pulse of EUV radiation. The radiation source may also be constructed to have a low inductance, and operated in a self-triggering regime.

  • Patent number: 6933510
    Abstract: A radiation source unit is provided that includes an anode and a cathode that are configured and arranged to create a discharge in a substance in a space between said anode and cathode and to form a plasma so as to generate electromagnetic radiation. The substance may comprise xenon, indium, lithium, tin or any suitable material. To improve conversion efficiency, the source unit may be constructed to have a low inductance, and operated with a minimum of plasma. To, for example, improve heat dissipation, a fluid circulation system can be created within the source volume and a wick by using a fluid in both its vapor and liquid states. To, for example, prevent contamination from entering a lithographic projection apparatus, the source unit can be constructed to minimize the production of contamination, and a trap can be employed to capture the contamination without interfering with the emitted radiation.

  • 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: 6818912
    Abstract: A radiation source includes an anode and a cathode for creating a discharge in a vapor in a space between anode and cathode and to form a plasma of a working vapor so as to generate electromagnetic radiation. The cathode defines a hollow cavity in communication with the discharge region through an aperture that has a substantially annular configuration around a central axis of said radiation source so as to initiate said discharge. A driver vapor is supplied to the cathode cavity and the working vapor is supplied in a region around the central axis in between anode and cathode.
