Interesting tsmc Yield Percentile Benchmark in Overseas Fabs

From these charts, it looks like tsmc overseas Fabs (JPN and US) ramped up quite good.

Well you see you are wrong. Morris Chang and the echo chamber of the internet said American worker are stupid dumb and lazy, and what Taiwan has cannot be replicated. Your data is invalid :cool:

Why? If anything yield should have started about where Taiwan is right now since TSMC said for their foreign fabs they would be using Copy Exactly! Erm I mean Global giga fab ™️. The fact it didn't is extremely concerning. The only alternative is the time is not adjusted with an offset between the alpha fab and the new fab and the difference between the top and bottom of the graph is like a 2% yield delta. Which I guess is possible, but hard to imagine given how useless/misleading a plot like that would be.

The NYTimes had reported that they had brought in a lot of folks from Taiwan to Arizona so Morris Chang would still contend that he is right :).

LOL, it was the local hires, those in the know 90% of the work done by the 60% assignees. They were beaten too do the work of the locals

This is a funny plot, I am surprised how low the starting point of the overseas. The right plot would be to show the yield or dd for the life of N4 and N22 a show the matching of the high volume mother fab. They’d each start higher up on the reference curve, with a fast ramp to match.
