    Abstract: PROBLEM TO BE SOLVED: To reduce fast ions in a plasma radiation source.SOLUTION: The radiation source includes a first activation source to direct a first energy pulse onto a first spot in the radiation source near discharge space to create a main plasma channel which triggers discharge. The radiation source also has a second activation source to direct a second energy pulse onto a second spot in the radiation source near the discharge space to create an additional plasma channel. By directing the second energy pulse during the same discharge, a shortcut of a main plasma current is realized, which can reduce an amount of fast ions to be produced.

    Abstract: PROBLEM TO BE SOLVED: To improve the lithography performance of an apparatus having a liquid that fills the space between a final element of a projection system and a substrate. SOLUTION: A lithographic apparatus and a device manufacturing method make use of a high-refractive index liquid, confined in a reservoir 13, at least partly filling a lithography field between a final element of a projection lens and the substrate. Bubbles forming in the liquid resulting from dissolved atmospheric gases or the gas discharge from an apparatus element exposed to the liquid are detected and removed so that they do not interfere with the exposure, to cause burning defects on the substrate. The detection can be carried out, by measuring the frequency dependence of ultrasonic attenuation in the liquid and the removal of bubbles can be implemented by: degassing and pressurizing the liquid; isolating the liquid from the atmosphere; supplying a continuous flow of liquid through the lithography field using liquids of low surface tension; and further, phase-shifting the ultrasonic standing-wave nodes.

    Abstract: PROBLEM TO BE SOLVED: To control fuel droplets by a method reducing potential contamination on other surfaces in a radiation source and other parts of a lithographic apparatus.
    SOLUTION: The radiation source is configured to generate extreme ultraviolet rays. The radiation source comprises a laser which is configured to generate a radiation beam to be guided to a plasma generation part for plasma generation when the radiation beam interacts with fuel, an optical component comprising a surface which is configured and positioned to be hit with droplets of the fuel, and a temperature conditioner configured to raise the temperature of the surface. A coating may be so provided on the surface as to change at least one nature of the surface. The energy source may be configured so that the droplets of fuel solidify before they hit the surface or to prevent the droplets of fuel from vaporizing.

    Abstract: PROBLEM TO BE SOLVED: To prevent damage to a component of a lithography apparatus, in particular, a mirror located nearby a plasma source due to contaminant particles. SOLUTION: The lithography apparatus includes a radiation source which generates extreme ultraviolet radiation. The radiation source includes a chamber in which plasma is generated and the mirror which reflects radiation emitted by the plasma. The mirror includes a multilayer structure including an Mo/Si alternation layer. A border Mo layer or border Si layer or a border diffusion barrier layer of the alternation layer forms an uppermost layer of the mirror, and the uppermost layer faces the chamber inward. A hydrogen group generator generates hydrogen in the chamber. The hydrogen group removes debris, generated from the plasma, from the mirror. COPYRIGHT: (C)2010,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a lithographic projection apparatus in which an ML condenser has been substituted by a condenser that can form a radiation beam by collecting a radiated light within a solid angle which is equivalent to the solid angle within which the ML condenser collects the radiated light.
    SOLUTION: The lithographic apparatus to be disclosed includes a radiation source that emits the radiated light and at least one condenser (59; 63; 73) that collects the radiated light by being arranged close to the radiation source (51) and forms a radiated beam (52). The at least one condenser includes a first reflector on a concave-face mirror (53) and a second reflector on a convex-face mirror (55). The concave-face mirror (53) is arranged surrounding the convex-face mirror (55). The first reflector on the concave-face mirror (53) receives the radiated light from the radiation source (51). The first reflector reflects the received radiated light toward the second reflector on the convex-face mirror (55) to form a beam of the radiated light (52).
