The reason Intel was "stuck" at 14 nm was because it took Extreme ultraviolet lithography (EUV) many years longer to become viable than was predicted. Prices may have more to do with the EUV market being dominated by ASML which has serious trouble producing lithography machines fast enough to meet demand.

No, Intel was "stuck" at 14 nm because they believed that they will succeed to scale down the transistor sizes a lot more, without using EUV, as Pat Gelsinger has just explained in a long interview in the Verge.

However they failed to implement with good results the methods that they had hoped to work, while the others, i.e. TSMC and Samsung had much more realistic roadmaps, which added EUV at the right moment.

Intel was not stalled by waiting for EUV, on the contrary they were not prepared for the transition that was necessary when EUV was eventually ready.

If it’s not one thing it’s another.

If progress continues then they will need some other expensive machine. Either that or they’ll try to stretch the life of EUV the same way Intel tried to delay EUV with extreme multiple patterning.

It seems to me though that the ASML machines ought to get some competition from something more like a free electron laser.
