3 separate shifts iirc. But don't Intel run 24/7 too? Or is that just for prod? I remember some plant (not Intel, a memory plant) had an issue and lost power for a few hours and lost a shite load of memory wafers and took a couple days to come back into prod.

Intel certainly do run machines 24/7 but perhaps those R&D engineers/PhD's don't, so maybe only the techie's running the machines have full coverage...?

Considering the overall investment goes into dozens of billions, it seems a little hard to believe they wouldn't source worldwide talent to make it 24/7 as well. Also they probably source top talent. I'm always skeptical of those "we just work a little harder" explanations.

I think you are really overshooting. Most people don't even know where their water comes from. Most people that drive do not know how a combustion engine works. Even people watching TV are only vaguely aware it's a series of static images chained together to make it look like its moving.

Wait, how am I overshooting? Reading your comment it seems like we are both in agreement. Or did I read you wrong?

I think they're trying to say that "people don't understand CPUs" is almost over-optimistic given how many much simpler things they don't understand.

Would perhaps have been better phrased as "Absolutely true, but it's even worse than that" ass-u-ming I parsed it right.

You're in agreement, they are additionally implying that the bar is much lower than you set it though.

Taiwan has invested in it like it was it's military. And it worked, they got to the point that the US would defend them from a Chinese invention.

Are you saying that once the US has moved TSMC over to the US then the US will stop caring about Taiwan?

If TSMC wasn't around, I think it could be argued that China would have tried to take over/invaded long before now. So if you are the government of Taiwan, helping TSMC out is in your best interest.

So are you saying that the US is actively trying to get invaded by moving TSMC out of Taiwan?

A recent interview with Shang-Yi Chiang, former Vice President of R&D at TSMC (also held positions at TI, HP, and SMIC) had insightful commentary on the speed of bringing up a new node. "We all take two years to develop one generation, how come you guys can do it in one or one-and-a-half year?" And they asked if some of your customer transfer technology to you or what not? And I told him, "No," I told him that, "That…

This is a made up explanation because: 1) All RnD fabs move wafers 24/7 2) Intel has consistently been the leader in process technology for 20+ years. Why did this “3x shift advantage” deliver gains only in the past 5 years?

It's not the whole story, sure, things are complex... but I think you calling it "made up" is a bit absurd. I'd attribute most of the lack of competition with Intel to a lack of capital; which, thanks to the success of TSMC's largest customers (who directly compete with Intel) Apple and AMD is no longer a problem.

Intel did have a huge advantage on everyone else 20 years ago, but ten years ago they more or less started sitting on their asses, and the rest of the world caught up and is passing them by. I don't know why something simple like running 24/7 R&D would not explain it.

Semiconductor industry has the deepest and most complex value chain in the economy. TSMC has always been pure fab company and it pays off now. Samsung and Intel are also in chip design business and do other things. They are less focused. TSMC's lead is not guaranteed. Any new technology node can fail and remove them from competition if they make wrong choices. I'm not exaggerating when I say that designing a new tech…

A bit of an aside, but your comment made me realize how much we don’t know about the process used to create the technologies that underpin our civilization. We (laymen) have no idea about the incredible complexity behind manufacturing a single CPU chip.

Oh boy, you should check out the show "Connections" by James Burke

I read it could also be volume. Higher volume means more data to learn from.

I was under the impression that it’s unusual for fabless chipmakers to do transistor level design anymore, and that they mostly rely on the standard TSMC libraries. But I may be wrong about that. The critical point I was trying to make is that the ASML machine doesn’t know how to make transistors. That’s something TSMC does: https://www.anandtech.com/show/16041/where-are-my-gaafets-ts...

No that's definitely not the case. For digital design, in general, you're not doing anything transistor-level. But those digital designers are using standard cell or memory libraries which are created at a transistor level. I believe the foundries also charge for their own standard cell libraries, and there are many other vendors that a design company can choose from like cadence, synopsys, even ARM. For analog/RF de…

Since you seem to know a lot about this--could Apple (or Cadence or ARM) create custom transistors on TSMC's process?

I think there's a good chance of markedly decreased interest, yes.
