As the mass production of semiconductors using EUV lithography began in earnest, actinic tool that applied various types of EUV source became necessary. Each EUV source has its own pros and cons, and for this reason, the actinic tools to which each EUV source can be applied are different, and no one EUV source is suitable for all actnic tools. In this presentation, we will focus on the EUV source applied to the actnic tool being developed by ESOL, but there will be an explanation of which EUV source is suitable for which actnic tool by adding other types of EUV sources.
