Leon Levasier, Fellow at ASML

Leon Levasier

Future-proofing ASML’s product roadmaps, focused on customer needs

"It's been a privilege to be a part of the EUV story – it's a collaborative effort on a truly grand scale. In my view, our EUV systems are the most complex machines in the world today."

Leon Levasier is appreciated inside and outside ASML as an overlay expert making a substantial contribution to the realization of the overlay roadmap for lithography systems.


The combination of Leon’s system knowledge and ability to come up with practical solutions enables him to also make an impact beyond the overlay roadmap as an expert in overall lithography scanner design.
