ASML was one of the founding partners in Albany NanoTech in collaboration with SEMATECH which became the Upstate NY Semiconductor Cluster back in the mid-2000s [0][1].
It was out of SEMATECH that DUV and EUV Photolithography was productionized and licensed to ASML.
Much of the underlying IP used by ASML is licensed and firewalled under JVs with the US DoE and/or the SUNY Consortium (primarily their D/EUV light source work) or firewalled and export controlled by Taiwan (primarily their metrology work)
Btw, that tidbit has become one of the main vetting techniques I use now to see whether someone is blowing hot air or has actual experience in the Semiconductor industry.
