"Fab" seems a bit of an overstatement. What he is describing is similar in capabilities to what any average university lab with a device fabrication facility is capable of.
A bit less, e-beam has significant limitations in the amount of area that you can cover at once (and is much slower than EUV). Not really suitable for anything besides prototypes and very small series. But once you have a prototype and it works you have the level of validation required to throw real money at a project.
I’m pretty sure that’s what they will do initially and once they get proof of concept they will seek funding for large scale. They will need a huge investment to get going on any sort of scale.
