Hi Labmembers and ASML users, 

I am creating a mask for ASML using PM alignment marks. Does anyone know if it matters when the PM mark is close to the design patterns? I will have a design about 200um away from the PM marks. If you can comment on the feasibility and potential issues, that would be really appreciated. 

Thanks a lot!
