摘要: The invention relates to a two-stage laser system well fit for semiconductor aligners, which is reduced in terms of spatial coherence while taking advantage of the high stability, high output efficiency and fine line width of the MOPO mode. The two-stage laser system for aligners comprises an oscillation-stage laser (50) and an amplification-stage laser (60). Oscillation laser light having divergence is used as the oscillation-stage laser (50), and the amplification-stage laser (60) comprises a Fabry-Perot etalon resonator made up of an input side mirror (1) and an output side mirror (2). The resonator is configured as a stable resonator.

摘要: An extreme ultraviolet (EUV) light source apparatus in which a location or posture shift of an EUV collector mirror can be detected. The apparatus includes: a chamber; a target supply mechanism for supplying a target material into the chamber; a driver laser for irradiating the target material with a laser beam to generate plasma; a collector mirror having a first focal point and a second focal point, for reflecting light, which is generated at the first focal point, toward the second focal point; a splitter optical element provided in an optical path of the light reflected by the collector mirror, for splitting a part of the light reflected by the collector mirror; and an image sensor provided in an optical path of the light split by the splitter optical element, for detecting a profile of the light split by the splitter optical element.
