ExCITe T406 – WP 1 - EUV Resist Technology Quarterly Meeting Athens, 11/ Resist Materials Characterization Work in ExCITe W.-D. Domke; Infineon ExCITe/More Moore Meeting May 12, 2005 Athens, Greece
ExCITe T406 – WP 1 - EUV Resist Technology Quarterly Meeting Athens, 11/ Status & Plans of Infineon Materials Characterization Bulk EUV litho characterization of relevant resist platforms done model resist formulation (outgassing, scissioning,..) on hold characterization of polymer side reactions finished and reported –correlation of chain scissioning and outgassing in EUV Open frame tool TEUVL available; further plans to be determined
ExCITe T406 – WP 1 - EUV Resist Technology Quarterly Meeting Athens, 11/ WP 1: EUV Resist Technology Open Frame Exposures Bulk Litho Characterization of main Resist Classes done (M1.1.5 & M1.1.7): Most investigated chemical platforms are viable for EUV patterning, no clear advantage could be found for either 193nm or 248nm type resists/polymers. Pilot EUV samples (Clariant EXC20 & EXC21; M1.1.6) are available Resolution down to 40nm shown with EUV Interference Lithography
