Intel fabs plenty of stuff at the 22 nm node, including chipsets for their CPUs[1], RF and other analog uses[2], novel RAM technologies, and their Lakefield/Foreveros thing. Given Intel's expanding product portfolio, there's likely additional internal customers for older nodes.

- petra 6y agoIs that enough volume to cover all of their older , and large, fab capacity ? i'm not so sure.
- wmf 6y agoIntel has a large number of fabs and I think capacity is reallocated over time; for example, a 22nm fab might be converted to 10nm to adapt to changing demand. They can eventually get down to just one 22nm fab which won't require as much demand to fill.
- ENOTTY 6y agoTo be fair, there are limits on how far and how fast one can upgrade a fab and upgrades are planned out many years in advance. Equipment for the smaller nodes tends to be larger and more complex and involving more steps; this requires more space. Additionally, ASML only makes around a dozen of the EUV machines each year and they are booked years in advance.
- petra 6y agoWhat percentage of the equipment changes between nodes ? Is it mostly the lithography and inspection tools ?
