Abstract

A catoptric system having a reference axis and first, second, and third reflectors. The first reflector contains a pattern-source carrying a substantially one-dimensional pattern. A combination of the second and third reflectors is configured to form an optical image of the pattern, with a demagnification coefficient N > 1 in extreme UV light, and with only two beams of light that have originated at the first reflector as a result of irradiation of the first reflector with light incident upon it. An exposure apparatus employing the catoptric system and method of device manufacturing with the use of the exposure apparatus.
