摘要： A radiation source generates short-wavelength radiation, such as extreme ultraviolet radiation, for use in lithography. Rotating electrodes are provided which dip into respective baths of liquid metal, for example, tin. An electrical discharge is produced between the electrodes to generate the radiation. Holes are provided in the electrodes and/or in a metal shielding plate around the electrodes to enable better pumping down to low pressure in the vicinity of the discharge to improve the conversion efficiency of the source. The holes in the electrodes improve cooling of the electrodes by causing stirring of the liquid metal, and by improving the thermal and electrical contact between the electrodes and the liquid metal. Improved electrical contact also reduces the time-constant of the discharge circuit, thereby further improving the conversion efficiency of the source.

摘要： A lithographic apparatus is arranged to project a beam from a radiation source onto a substrate. The apparatus includes an optical element in a path of the beam, a gas inlet for introducing a gas into the path of the beam so that the gas will be ionized by the beam to create electric fields toward the optical element, and a gas source coupled to the gas inlet for supplying the gas. The gas has a threshold of kinetic energy for sputtering the optical element that is greater than the kinetic energy developed by ions of the gas in the electric fields.

摘要： 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.

摘要： A lithographic apparatus is disclosed. The lithographic apparatus includes an illumination system that provides a beam of radiation, and a support structure that supports a patterning structure. The patterning structure is configured to impart the beam of radiation with a pattern in its cross-section. The apparatus also includes a substrate support that supports a substrate, and a projection system that projects the patterned beam onto a target portion of the substrate. The illumination system includes a radiation-production system that produces extreme ultra-violet radiation, and a radiation-collection system that collects extreme ultra-violet radiation. Particles that are produced as a by-product of extreme ultra-violet radiation production move substantially in a particle-movement direction. The radiation-collection system is arranged to collect extreme ultra-violet radiation which radiates in a collection-direction, which is substantially different from the particle-movement direction.
