Since 1996, the program of the research and development (R&D) on EUVL has begun at the Laboratory of Advanced Science and Technology for Industry, Himeji Institute Technology (HIT) (present University of Hyogo) using the NewSUBARU synchrotron light source. For EUV resists, it was prepared that 1) the high-precision-resist-sensitivity evaluation tool, 2) the outgassing testing with quadrupole mass spectrometry and carbon contamination growth measurement with in-situ ellipsometry, 3) the transmittance measurement tool, and 4) the EUV interference lithography in 10 nm hp pattering. Recently, it is prepared that toward low LWR achievement by 1) the resonant soft X-ray scattering (RSoXS) in the transmission mode and 2) PEEM to evaluate the chemical contents spatial distribution, and 3) the out-of-band (OoB) reflectometer and transmittance measurement tool. In addition, it is prepared that the RSoXS in the reflectance mode to evaluate layer analysis preventing from pattern collapse.
