Terafab Strategies to Bypass ASML EUV Lithography Bottlenecks
Coverage highlights the critical challenge of ASML's EUV lithography machine backlogs and Terafab's approaches to circumvent supply constraints through massive scale and custom chip designs.
Key facts
- ASML's perpetual order backlog hinders rapid fab scaling for projects like Terafab
- Terafab leverages extreme physical scale to design chips beyond traditional size and thermal constraints faced by Nvidia and others
- Global EUV tool shortages and U.S. talent gaps in semiconductors pose feasibility risks
For a massive new project like TERAFAB to hit the ground running, Musk needs a way to bypass the ASML bottleneck.

GaN operates under a different set of physical rules. It can handle significantly higher voltages, temperatures, and frequencies than silicon. Because of these inherent material advantages, highly efficient GaN chiplets can be manufactured on slightly more mature nodes using widely available Deep Ultraviolet (DUV) lithography equipment.

- asiatimes.com ASML as the last polite monopolist - Asia Times TSMC’s highly unusual public complaint of ASML’s latest EUV pricing falls in that category. Not only because the “very very expensive” complainer is relentless in utilizing its own pricing power, but also because it is not usual for these institutions to wash their dirty linen in public. We had discussed the near-monopsony and near-monopoly clash one sees in the TSMC and ASML battle first in 2024.
