I just want to provide some background - - -
1. Morris Chang (born 1930) IS THE VLSI FOUNDRY BUSINESS INVENTOR.
2. He came to the USA from Taiwan and attended Harvard, Stanford, and MIT.
3. Morris Chang became a USA citizen in 1962. Currently he works in Taiwan.
4. He invented the foundry business idea at TI in the 1980s, but they didn't want to become a foundry.
5. He returned to Taiwan and convinced the government to invest in his project.
6. He has worked for more than 50 years on his idea and deserves our great respect.
I was at the largest TSMC foundry in December (in Taiwan). Don't blame TSMC for the high costs of VLSI production. The high costs are a symptom that Moore's Law is ending. What happens at the end of Moore's Law is that foundry costs go up faster than VLSI gets better / cheaper / faster. And we are in that phase now. I truly believe that without TSMC, we'd be 1.5 generations behind in VLSI, everyone with a GPU would have an RTX3000 card or a RX6000 card, everyone with a CPU might have an AMD 5800x. Thank you, TSMC.
One of the main reasons that Intel is doomed is because VLSI costs are going up faster than ANY OF THEIR BUSINESSES ARE GROWING. Under these circumstances, you can hire the most brilliant engineers in the world and it won't matter. You must become a foundry and start taking outside customers. Morris Chang knew this in the 1980s. Intel is still too stupid to realize that it's their only choice, and they have dragged their ass for 20 years in recognizing this fact !!
TSMC needs MONSTER PROFITS to build a next generation fab. They need to save up $30B for their next-generation 2N fab, with annual operating costs of $3B. It's a gigantic gamble that nobody wants to finance. So yes, they have 40% profit margins, but what if I told you 38% of those margins were saved so they could continue to improve VLSI? Would you fault them for that ??
Each new generation of fab costs about 30-50% more than the previous generation. Costs at TSMC are going up exponentially. If the new fab is not exponentially better than the old one (with a HIGHER exponent), VLSI ends, it's kaput, no more improvement in VLSI, computers, GPUs, AI, nothing gets faster. Let that sink in. VLSI is currently mankind's greatest endeavor in history - our greatest struggle against Nature. Let that sink in ...
