To keep in pace with the highly accelerated speed of development of EUV resists, the use of the pressure rise method in the screening of EUV resist outgassing was utilized. This method was used for its advantage of in-situ applicability and evaluation speed (short evaluation time). Both “outgassing rate” [molecules/cm2/s] and “outgassing amount” [molecules/cm2] unit conventions have been obtained. In the conference, an overview of the latest EUV resist outgassing analysis results using various EUV resists (i.e. chemical amplified, PHS, acrelate, high Ea, low Ea, negative-tone, molecular, etc.) will be discussed in detail.
