18 March 2016 NXE pellicle: offering a EUV pellicle solution to the industry

Abstract
Towards the end of 2014, ASML committed to provide a EUV pellicle solution to the industry. Last year, during SPIE Microlithography 2015, we introduced the NXE pellicle concept, a removable pellicle solution that is compatible with current and future patterned mask inspection methods. This paper shows results of how we took this concept to a complete EUV pellicle solution for the industry. We will highlight some technical design challenges we faced developing the NXE pellicle and how we solved them. We will also present imaging results of pellicle exposures on a 0.33 NA NXE scanner system. In conjunction with the NXE pellicle, we will also present the supporting tooling we have developed to enable pellicle use.
