NXE Pellicle: Development Update

摘要

ASML introduced the NXE pellicle concept, a removable pellicle solution that is compatible with current and future patterned mask inspection methods. We will present results of how we have taken the idea from concept to a demonstrated solution enabling the use of EUV pellicle by the industry for high volume manufacturing. We will update on the development of the next generation of pellicle films with higher power capability. Further, we will provide an update on top level requirements for pellicles and external interface requirements needed to support NXE pellicle adoption at a mask shop. Finally, we will present ASML's pellicle handling equipment to enable pellicle use at mask shops and our NXE pellicle roadmap outlining future improvements.
