Outgassing Evaluation More Moore, SP3 WP6, for Task 3.6.1.6.1 and 3.6.2.3 Elettra and AZ Electronic Materials Athens 12.Mai 2005 Review Meeting More Moore_SP3-WP CONSORTIUM CONFIDENTIAL
Objectives for Outgassing • Low or no Outgassing chemicals is a requirement for the EUV exposure • tool shelf life • First specifications for outgassing are given by • ASML • Resist outgas specifications for Alpha tool: • H20 4.7E15 (molec/s*cm2) • CxHy(integr. > 44 AMU) 4.7E13 • F/Cl 4.7E14 • S/P 4.7E11 • Si 4.7E9 • PAG fragments (S/P) most critical • Intel Outgassing 5*1010 [molecules/cm²] at Esize (onlyinternal) Review Meeting More Moore_SP3-WP CONSORTIUM CONFIDENTIAL
Intel and Sematech are working on outgassing • test procedure for outgassing • characterization of of outgassing behavior of EUV resists and related materials:a) qualitativly • b) quantitativly • Outgassing experiments within More Moore and ExCite • are needed to have test equipment and to get experience • are needed to characterize the EUV resist materials • are needed for selection of appropriate EUV resist material.

Conclusion • PAGs, which create Perfluorsulfonic acids outgass under EUV with SO,SO2 • More data needed • Confirmation of reliability and precicion of measurement • Analyses of mass fragments • Quantification of outgassing in relation to specification of exposure tool Review Meeting More Moore_SP3-WP CONSORTIUM CONFIDENTIAL
