Characterization of EBL2 EUV Exposure Facility
INTERNATIONAL CONFERENCE ON EXTREME ULTRAVIOLET LITHOGRAPHY 2017(2017)
摘要
TNO has built EBL2; a facility for EUV exposure testing and surface analysis. EBL2 is capable of testing EUV optics, EUV photomasks, pellicles, and other components under controlled conditions, relevant to EUV scanner and source operation at all foreseen source power nodes. The system consists of an EUV beam line coupled to an X-ray Photoelectron Spectroscopy system by an automated sample handler. The current contribution reports on the results of the qualification testing of the EUV beam line. Topics investigated include handling and position control, thermal management, a relevant gas environment, EUV irradiation and metrology, and first EUV exposures.
