    摘要: A projection objective suitable for immersion microlithography is designed as a single-waist system with five lens groups, and has a first lens group of negative refractive power, a second lens group of positive refractive power, a third lens group of negative refractive power, a fourth lens group of positive refractive power and a fifth lens group of positive refractive power. The fourth lens group has an entrance surface (E) that lies in the vicinity of a point of inflection of a marginal ray height between the third lens group (LG3) and the fourth lens group (LG4). No negative lens of substantial refractive power is arranged between the entrance surface and the system diaphragm (5). Embodiments of inventive projection objectives achieve a very high numerical aperture NA>1 in conjunction with a large image field and are distinguished by a compact design size. For working wavelengths below 200 nm, structural widths of substantially under 100 nm can be resolved when use is made of immersion fluids between the projection objective and substrate.

    摘要: A projection exposure apparatus for the exposure of a radiation-sensitive substrate arranged in the region of an image surface of a projection objective with at least one image of a pattern of a mask that is arranged in the region of an object surface of the projection objective has a light source for emitting ultraviolet light from a wavelength band having a bandwidth Δλ>10 pm around a central operating wavelength λ>200 nm; an illumination system for receiving the light from the light source and for directing illumination radiation onto the pattern of the mask; and a projection objective for the imaging of the structure of the mask onto a light-sensitive substrate. The projection objective is a catadioptric projection objective having at least one concave mirror arranged in a region of a pupil surface of the projection objective, and a negative group having at least one negative lens arranged in direct proximity to the concave mirror in a region near the pupil surface, where a marginal ray height (MRH) of the imaging is greater than a chief ray height (CRH).
