Elon Musk's TeraFAB: The Ambitious Plan to Overcome ASML Bottlenecks

TERAFAB, the project spearheading this vision, aims to utilize resources from Tesla, SpaceX, and xAI to tackle the overwhelming demands of AI and space‑related technologies. This initiative highlights a strategic departure from traditional reliance on silicon‑based components due to bottlenecks faced with ASML's EUV lithography machines, essential for advanced chip fabrication.

Beyond EVs, Tesla has begun rolling out robotaxis, and it plans to sell its Optimus robot to consumers, potentially by the end of next year. On top of that, it has recently announced plans for a massive chip manufacturing facility, called the Terafab, which will help generate the computing power that's necessary for not only Tesla but also SpaceX and xAI -- Musk's other companies.

That specific shrinking process requires ASML's most advanced, heavily backlogged EUV machinery. 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. By leaning heavily into GaN architectures, TERAFAB can side
