Abstract

The study presented here was initiated by a discussion to investigate the possibility of using synchrotron radiation as a source for the Next Generation Lithography (NGL) based on the EUV-concept (Extreme Ultra-Violet; here 13.5 or 11.3nm radiation, respectively). The requirements are: 50 W, 2%, bandwidth and minimal power outside this bandwidth. Three options were investigated. The first two deal with radiation from bending magnets and undulators. The results confirm the earlier work by Oxfords Instrument and others that these light sources lack in-band power while emitting excessive out-of-band radiation. The third approach is a Free Electron Laser (FEL) driven by a 500MeV linear accelerator with a superconducting mini-undulator as radiation emitting device. Such as device would produce in-band EUV-power in excess of 50W with negligible out-of-band power. © 2001 Elsevier Science B.V. All rights reserved.
