TSMC's 2nm process will reportedly get another price hike — $30,000 per wafer for latest cutting-edge tech
2nm to cost 2X more than 4nm and 5nm

This is what a lack of competition looks like.
However.... Twice the price of 4nm? The gains are fairly marginal from what I gather. I don't think many will bother.
It's both lack of competition and the end of Moores law. We've effectively reached the end of silicon gate sizes and the tooling complexity required to keep shrinking process nodes and increase transistor density is increasing exponentially, so semiconducters no longer get cheaper... and it's starting to push these cutting edge nodes outside of economic viability for consumer products. I'm sure TSMC is taking a very healthy profit cut for sure but the absolute magic they have to work to have 2nm work at all is beginning to be too much.
the end of Moores law
It's been talked about a lot. Lots of people have predicted it.
It does eventually have to end though. And I think even if this isn't the end, we're close to the end. At the very least, we're close to the point of diminishing returns.
Look at the road to here-- We got to the smallest features the wavelength of light could produce (and people said Moore's Law was dead), so we used funky multilayer masks to make things smaller and Moore lived on. Then we hit the limits of masking and again people said Moore's Law was dead, so ASML created a whole new kind of light with a narrower wavelength (EUV) and Moore lived on.
But there is a very hard limit that we won't work around without a serious rethink of how we build chips- the width of the silicon atom. Today's chips have pathways that are in many cases well under 100 atoms wide. Companies like ASML and TSMC are pulling out all the stops to make things smaller, but we're getting close to the limit of what's possible with the current concepts of chip production (using photolithography to etch transistors onto silicon wafers). Not possible like can we do it, but possible like what the laws of physics will let us do.
That's going to be an interesting change for the industry, it will mean slower growth in processing power. That won't be a problem for the desktop market as most people only use a fraction of their CPU's power. It will mean the end of the 'more efficient chip every year' improvement for cell phones and mobile devices though.
There will be of course customers calling for more bigger better, and I think that will be served by more and bigger. Chiplets will become more common, complete with higher TDP. That'll help squeeze more yield out of an expensive wafer as the discarded parts will contain fewer mm^2. Wouldn't be surprised to see watercooling become more common in high performance workstations, and I expect we'll start to see more interest in centralized watercooling in the server markets. The most efficient setup I've seen so far basically hangs server mainboards on hooks and dunks them in a pool of non-conductive liquid. That might even lead to a rethink of the typical vertical rack setup to something horizontal.
It's gonna be an interesting next few years...
No, there's still competition. Samsung and Intel are trying, but are just significantly behind. So leading the competition by this wide of a margin means that you can charge more, and customers decide whether they want to pay way more money for a better product now, whether they're going to wait for the price to drop, or whether they'll stick with an older, cheaper node.
And a lot of that will depend on the degree to which their customers can pass on increased costs to their own customers. During this current AI bubble, maybe some of those can. Will those manufacturing desktop CPUs or mobile SoCs be as willing to spend? Maybe not as much.
Or, if the AI hype machine crashes, so will the hardware demand, at which point TSMC might see reduced demand for their latest and greatest node.
Dangerous game considering Intel should be coming up with their 18A node pretty soon now, and it will supposedly be competitive with TSMC's 3nm or 2nm according to rumors. They will only need to compete in price, and if they are competitive in performance, and TSCM is increasing their prices so much, it would be a good way for Intel to take some of that market share.
you have practical, working tsmc chips plus next-gen r&d versus theoretical chips from Intel, a company that has not fared well over 30 years of trying to catch up with TSMC.
they're not worried yet.
Intel has only been behind for the last 7 years or so, because they were several years delayed in rolling out their 10nm node. Before 14nm, Intel was always about about 3 years ahead of TSMC. Intel got leapfrogged at that stage because it struggled to implement the finFET technology that is necessary for progressing beyond 14nm.
The forward progress of semiconductor manufacturing tech isn't an inevitable march towards improvement. Each generation presents new challenges, and some of them are quite significant.
In the near future, the challenge is in certain three dimensional gate structures more complicated than finFET (known as Gate All Around FETs) and in backside power delivery. TSMC has decided to delay introducing those techniques because of the complexity and challenges while they squeeze out a few more generations, but it remains to be seen whether they'll hit a wall where Samsung and/or Intel leapfrog them again. Or maybe Samsung or Intel hit a wall and fall even further behind. Either way, we're not yet at a stage where we know what things look like beyond 2nm, so there's still active competition for that future market.
Edit: this is a pretty good description of the engineering challenges facing the semiconductor industry next:
They aren't going to be competitive in their foundry with them laying off so many experienced operators. I work at a fab down the street from intel and our hiring classes went from 10 every other week to 20-30 now.
They can drop the price the day Intel actually puts a chip on the market... They're capturing maximum profit while they can.
Capitalism baby!
I wonder if it has anything to do with the hurricane.
