I will get some recent input from experts on this. But my take is that it can take twice as long but a lot of that depends on the company doing it. Supply chain and labor availability in asia is much better. I would be shocked if it actually cost 2x as much ... my spreadsheet is nowhere near that big a difference. Tools are still the largest part of capital expense. All this assumes the same subsidies. In the past, other countries gave huge subsidies and the US gave few. that has changed.
What are your thoughts
@nghanayem or
@Scotten Jones ?
Reminder: NEVER use the publicly stated costs to build a fab that companies publish. Those are meant to get the response they want from government. the actual spending is accurately tracked by a number of sources if you talk to the correct people.
