The fab that Infineon is building is vastly smaller in scale, and their tech isn't really relevant to this discussion. For instance, it doesn't produce CPU/GPU microchips or DRAM. Also only 300mm wafer technology, which isn't competitive for anything except for some narrow industrial use-cases. Glad to see the EU is doing it, but it's a completely different thing.

Pretty much everyone is on 300 mm wafers for everything now, and has been for a while. Are you perhaps reading this as 300 nm process (which would usually be called 0.3 micron)?
