That’s some big chips.😳
300mm (30 cm or 11 inch transistors / microprocessors) are, well, pretty much late 1940s / early 1950s technology, no?
I remember back in the 1990s when the technology media was saying that we would never be able to make a chip with smaller than 25 nanometer traces due to physics limits.
GF-STM have abandoned any process smaller than 14nm.
There is still plenty of demand for older technology.
Both IBM and AMD abandoned GF on 7nm as they couldn’t get it to work.
