摘要： A method for performing optical adjustments of an exposure apparatus is based on an exposure apparatus having a light source for generating illumination light for exposure, and illumination optics for irradiating a mask with the illumination light generated from the exposure light source so as to imprint a mask pattern on a substrate base. The apparatus uses a wide bandwidth light source for the exposure light source that produces exposure light and non-exposure light having wavelengths different from those in the exposure light, and optical adjustments for optical components in at least a portion of the illumination optics are performed by using non-exposure light

摘要： In a projection exposure apparatus used in lithography process for transferring a predetermined pattern formed on a reflection type mask onto a photosensitive substrate, the reflection mask and the substrate are moved relative to each other by a scanning driver, and the illumination optical system located between a radiation light source and the reflection mask includes a field stop located near a position conjugate with the reflection mask. In another embodiment a scanning driver changes the positional relationship between the reflection mask and the projection optical system, or/and between the substrate and the projection optical system. In another embodiment an image of the field stop is formed on the reflection mask by a relay optical system, preferably a catoptric system, forming the predetermined pattern. The projection optical system located between the reflection mask and the substrate directs the light reflected from the mask to the substrate, and illuminance distribution of the light on the exposure area of the substrate is adjustable by changing the position of reflection optical elements located along the optical path of the radiation light in the illumination optical system.

摘要： An illumination optical apparatus includes a light source, which supplies illumination light including a wavelength of 5 nm to 50 nm, and an illumination optical system, which guides the illumination light to an illuminated surface. The illumination optical system includes an aperture angle restriction member and a condenser optical system, which is arranged in an optical path between the aperture restriction member and the illuminated surface to guide light beam from the aperture angle restriction member to the illuminated surface. A rotation axis of an arcuate-shape of an illumination region formed on the illuminated surface is located outside an opening of the aperture angle restriction member. The condenser optical system includes a plurality of reflection surfaces. Among the plurality of reflection surfaces, the reflection surface closest to the illuminated surface along the optical path includes a concave shape. When, for example, applied to an EUVL exposure apparatus, the illumination optical apparatus illuminates a reflective mask, serving as the illumination plane, without a plane mirror in the optical path between the illumination optical system and the mask.

摘要： A projection optical system is a catoptric system in which a field of view region and an imaging region are located spaced from an optical axis, in which a numerical aperture of light reaching each point on an image plane is substantially uniform regardless of an image height and a direction. An aperture stop for defining the numerical aperture of the projection optical system is provided, and the aperture stop is provided with an aperture portion in a predetermined shape in which the numerical aperture of light reaching each point within a predetermined region is substantially uniform over the predetermined region, that is, in a shape in which dimensions concerning two directions perpendicular to each other are different from each other. A predetermined shape of the aperture portion is defined so as to compensate for the effect of non-uniformity of the numerical aperture of light reaching each point within a predetermined region due to a partial optical system arranged between the aperture stop and an image plane not satisfying a desired projective relationship.
