“I like reducing friction, whether between wafer and scanner or between teams. Bringing concepts to life takes commitment, resilience and close cooperation.”
Constans Weber was made an ASML Fellow for his expertise in coatings to extend the lifetime of wafer tables in lithography systems. But among colleagues and external partners, he is recognized as much for his interpersonal skills and leadership qualities as for his technical excellence and professional dedication.
Constans led ASML’s participation in a multi-organization project to apply diamond coatings to highly sensitive surfaces. Carried out largely during the COVID period, the project faced huge logistical as well as technical challenges. However, Constans’s exceptional technical competence, resilience and cross-functional leadership helped deliver a successful high-volume process that could enable wafer tables that last for the lifetime of the system.
