摘要:
A projection exposure apparatus (10) for forming an image of a pattern present on a first object such as a reticle (R) onto a second object, such as a wafer (W). The apparatus comprises along three optical axes (AZ1, AX, AZ2), an illumination optical system capable of illuminating the reticle with partially polarized light, and a catadioptric projection optical system (40-70) arranged adjacent the reticle and opposite the illumination optical system. The catadioptric projection optical system comprises one or more substantially spherical mirrors (48), a plurality of refractive members (42, 48, 72, 74), and one or more plane mirrors (60, 66). The plane mirrors are designed and arranged so as to allow a substantially unpolarized image of the reticle pattern, which is illuminated with partially polarized light, to be formed on the wafer.

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.

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
