Research Abstract

We have quantitatively investigated the relation between the energy fluence of the EUV laser and the ablation threshold of substances and have developed key technologies toward nano-fabrication using EUV laser. We also investigated the method to increase the EUV laser power and to expand the wavelength range to shorter wavelength region.
