Headquartered in Dortmund, RAITH GmbH develops maskless nanofabrication and characterization systems for research and industrial device production. Its high-precision electron-beam and laser lithography tools, alongside imaging and analysis systems, support work in fields such as semiconductors, photonics and quantum technology. RAITH combines more than 40 years of nanofabrication experience with a global network of offices, experience centers and service specialists.
TESCAN GROUP, a.sFrom its home in Brno’s electron-optics tradition, TESCAN GROUP, a.s. makes imaging and analysis instruments for scientific and industrial research, including electron microscopes, micro-CT and focused-ion-beam systems. Founded in 1991 by former Tesla engineers, the company has spent more than 35 years turning complex microscopy workflows into practical tools used in more than 80 countries. Now part of Shimadzu Corporation, Tescan also develops specialized systems such as the FemtoChisel femtosecond laser for semiconductor sample preparation and failure analysis.423490WARRENDALE, PA
Nabu Optical SystemsFounded in 2022 from University of Dayton photonics research, Dayton-based Nabu Optical Systems develops maskless optical lithography tools for semiconductor prototyping and production. Its platform uses virtual masks to combine projection lithography’s speed with direct laser writing’s flexibility, serving startups, research institutions and smaller chip manufacturers that need a more accessible path to fabrication. The company won the startup competition at the 2025 International Conference on Electron, Ion, and Photon Beam Technology and Nanofabrication.DUBLIN, OH
Applied Research & Photonics, IncFrom its Harrisburg base, Applied Research & Photonics develops terahertz spectrometers and provides non-contact, non-destructive testing for semiconductor and nanomaterial research. Its TeraSpectra and TNS3DI systems combine spectroscopy with subsurface, layer-by-layer 3D imaging to locate defects within materials rather than only viewing their surfaces. The company’s work has received recognition including the 2011 CLEO/Laser Focus World Innovation Award and NASA Tech Briefs’ 2008 Nano-50 Innovator Award for founder and CTO Anis Rahman.HARRISBURG, PA
