Paper Abstract

Gigaphoton Inc. is developing a CO2-Sn-LPP EUV light source based on unique and original technologies including a high power CO2laser with 15 nanosecond pulse duration, a solid-state pre-pulse laser with 10 picosecond pulse duration, a highly stabilized droplet generator, a precise laser-droplet shooting control system and a debris mitigation system using a magnetic field. In this paper, an update of the development progress of our 250W CO2-Sn-LPP EUV light source and of the key components is presented.
