Elon Musk on Wednesday said that TeraFab plans to use Intel's 14A fabrication technology when it has its own production capacity later this decade and when the manufacturing process matures. He also revealed that Tesla will be responsible for building and operating a pilot production line, whereas SpaceX will be responsible for high-volume manufacturing of chips.
"We plan to use Intel's 14A process, which is state-of-the-art and in fact not yet totally complete," Elon Musk, chief executive of Tesla, said during Tesla's earning's call with analysts and investors. "By the time TeraFab scales up, 14A will be probably fairly mature or ready for prime time. 14A seems like the right move and we have a great relationship with Intel, a lot of respect for the CEO, the CTO, and the new team there."
Based on the comments made by Musk, he wants to use Intel's 14A manufacturing technology at TeraFab, which likely means licensing the fabrication node from Intel and integrating it at a fab operated by TeraFab. Meanwhile, Musk has never mentioned licensing per se, which means that while Intel is expected to participate in TeraFab as a partner, actual details of its role have yet to be defined.

In the short term, Tesla intends to construct a semiconductor R&D facility at its Texas campus, with an estimated cost of around $3 billion. This site will be a small pilot line capable of processing a few thousand wafers per month, and its purpose will be to experiment with new ideas in semiconductor manufacturing as well as validate whether these ideas can be realized in a production-like environment. From what we can tell, 14A will barely have anything to do with the pilot line in Texas.
"In the near term, Tesla plans to build a research fab at its Gigafactory Texas campus," Musk said. "This is something we expect to be a $3 billion initiative and support a few thousand wafers per month. "It is really intended to try out ideas […] for improving the fundamental technology of how chips are made, some of new physics we would like to test out. We also want to test out the ability to see if something is working in production [environment]. You need kind of like a few thousand wafer starts a month to make sure that a production process is sound."
For scaling beyond the pilot phase, SpaceX is expected to build an actual high-volume manufacturing facility. However, coordination between Tesla and SpaceX introduces many challenges, as any joint effort must be approved by both companies' boards and pass conflict-of-interest reviews, which will inevitably slow down the project.
