@akatsuki6371 Overtaking DUV is a complicated question because foundries use the two machine alongside each other. DUV machines has higher throughput so EUV are only used on critical features that can only be done with EUV while using DUV for the rest. For example for the metal layers of a 7nm process. EUV is only use for the first and second layer. For 5nm the 3rd and 4th metal layer is also in EUV and smaller nodes will use them on even more layers. But Processor chips can have up to 12 to 14 metal layers. So DUV machines will not get abandoned. As process nodes that requires EUV grows they will still need DUV to complete the fabrication.

@akatsuki6371 They are economically viable. They are using this monster machines for several years now. The foundries raise their wafer prices but the chipmakers have enough margin to absorb the increase in price. It is very economically viable in fact that intel already ordered the version 2 an even larger monster machine.

@user_375a82 For EUV never but there are laboratory scale equipment that can do the similar or even better resolution but at a very slow rate.
