5nm is good yield at the moment. It's even fully automotive qualified, which is a testament to its yield. But performance advantage vs cost doesn't justify to move from 7nm for a lot of designs. So tech adoption is getting stickier. For hogh performance designs like Apple CPUs going to the cutting edge is a given. So since 3nm is available 5nm lost its appeal. This is a new territory for TSMC but I think they handled it well. Just last year they were gearing up a lot of 5nm capacity in anticipation of people moving from 12 and 7nm to 5nm. It quickly became clear that this isn't happening. So they moved some of this to 3nm and some is going back to 7nm and 6nm (shrunk 7nm) I think. They are also cautious about buying the newest equipment from ASML unlike Intel and Samsung. This seems to play well for TSMC. I think TSMC learned from Intel's downfall more than Intel. I don't see any industry traction from IFS. They can research any new technology they want. Without wafer orders it's a recipe for a quick cash burn..
