    摘要: A lithographic apparatus and device manufacturing method makes use of a high refractive index liquid confined in a reservoir 13 at least partly filling the imaging field between the final element of the projection lens and the substrate. Bubbles forming in the liquid from dissolved atmospheric gases or from out-gassing from apparatus elements exposed to the liquid are detected and removed so that they do not interfere with exposure and lead to printing defects on the substrate. Detection can be carried out by measuring the frequency dependence of ultrasonic attenuation in the liquid and bubble removal can be implemented by degassing and pressurizing the liquid, isolating the liquid from the atmosphere, using liquids of low surface tension, providing a continuous flow of liquid through the imaging field, and phase shifting ultrasonic standing-wave node patterns.

    摘要: A lithographic apparatus includes an illumination system for providing a beam of extreme ultra-violet radiation, a masking device for controlling the illumination of a patterning device by the beam of radiation, a support for supporting the patterning device, the patterning device configured to impart a pattern to the beam of radiation, a substrate table for holding a substrate, and a projection system for projecting the patterned beam of radiation onto a target portion of the substrate. The masking device includes a masking blade including a masking edge configured to delimit a boundary of an illumination region on the patterning device. The masking blade is configured to reflect extreme ultra-violet radiation incident on the masking blade such that at least a portion of the reflected radiation is not captured by the projection system.
