BIOGRAPHY
Erik Hosler has spent his career driving disruptive innovation across the semiconductor industry—from advanced lithography to quantum devices and silicon security. He began his career at GLOBALFOUNDRIES, where he led the EUV industrialization program that delivered initial 7 nm EUV yield at Fab 8 prior to the company’s strategic pivot. He then joined PsiQuantum, developing the initial patterning strategy for the company’s foundational silicon photonic quantum devices, including single-photon detectors and waveguide architectures.
Building on his experience in both high-volume manufacturing and deep-tech startups, Erik founded multiple companies centered on transformative semiconductor technologies. Leveraging his leadership of the semiconductor industry’s study group on FEL-based lithography sources since 2014, he founded xLight in 2021 to build the first commercially viable free-electron laser designed for ASML scanner integration. After establishing the company’s core technical team, strategic partnerships, and early integration roadmap, he was recruited to solve a rapidly growing industry challenge: end-to-end semiconductor authenticity and integrity.
In 2025, Erik founded OBSIDIA Semiconductors, the leading company enabling full-chain validation of device authenticity from wafer to end application, without added manufacturing steps or cost. OBSIDIA provides provenance, traceability, and tamper-detection across the entire semiconductor lifecycle.
Erik holds a Ph.D. in Physical Chemistry from the University of California, Berkeley. He has published widely on lithography, advanced patterning, and industrial FEL light-source technologies. He is an SPIE Senior Member, an Associate Editor of JM3, and currently serves as CEO of OBSIDIA Semiconductors.
