TSMC tells vendors to delay chip equipment deliveries
- lisper 3y agoThis makes absolutely no sense. A month ago the headline was "Apple buys every 3 nm chip that TSMC can make for next-gen iPhones and Macs" [1]. Six months ago it was a global chip shortage that had supply chains backed up around the planet. And now it's suddenly "the world's top contract chipmaker grows increasingly nervous about customer demand"? In the middle of a revolution in AI? Something doesn't add up here. https://arstechnica.com/gadgets/2023/08/report-apple-is-saving-billions-on-chips-thanks-to-unique-deal-with-tsmc/ https://arstechnica.com/gadgets/2023/08/report-apple-is-savi...
- ksec 3y ago>as the world's top contract chipmaker grows increasingly nervous about customer demand, two sources familiar with the matter said. I stopped reading after that. And as someone who knew about TSMC and ASML before 99.99999% of internet even start reporting news on TSMC. Most if not all of TSMC news are just plain BS.
- MrBuddyCasino 3y agoNvidia‘s H100 chips may sell for a lot of money, but in terms of wafers, its just around 10% of volume compared to their gaming chips. There is rarely a shortage that isn’t followed by an oversupply, so in fact it would be weird if it was different this time.
- SeanAnderson 3y agohttps://en.wikipedia.org/wiki/Bullwhip_effect https://en.wikipedia.org/wiki/Bullwhip_effect My naïve assumption is that it has to do with this?
- hef19898 3y agoThat one knows no mercy.
- chankstein38 3y agoI'm equally confused. I came here to say the same. One thing I'm not confident about is my understanding of this article. Is it, in fact, saying that they're slowing down production because they fear low consumer demand? I may have missed it in the article but I don't feel like it ever clearly states it like that. Def possible I just didn't read it well but I ended my review of it still confused about whether they were worried about lack of or increase in demand
- solardev 3y agoIt's a typical boom/bust cycle, isn't it? Plus tech is going through a recession, there's less money tossed around, inflation is cray cray, people have less disposable income, etc.
- ThrowawayR2 3y agoThe chip shortage was about common, low-cost chips made on older (i.e. larger), mature process nodes that TSMC does less business in. As for the "revolution in AI", TSMC isn't going to spontaneously manufacture chips that nVidia and AMD haven't ordered, so your "something doesn't add up" should be directed to them. The same goes for Apple.
- GeekyBear 3y agoI would imagine it has to do with the industry wide slump in demand that appeared earlier in the year. > Samsung Electronics plans to cut back memory chip production as its operating profit in the first quarter of 2023 is expected to plummet about 96% from the previous year. The global macroeconomic slowdown, memory chip oversupply and sluggish demand have hurt its profit, the world’s largest memory chip maker said in its preliminary earnings release on Friday. https://techcrunch.com/2023/04/06/samsung-cuts-memory-chip-production-as-it-hits-worst-quarterly-profit-since-2009/ https://techcrunch.com/2023/04/06/samsung-cuts-memory-chip-p... I think it took Samsung most of a year of production cuts to clear out excess inventory.
- ckastner 3y ago> Six months ago it was a global chip shortage that had supply chains backed up around the planet. chip != chip. TSMC manufactures hundreds of products, check out slide 4 of the last quarterly results [1]. "AI" (on 5nm or below) is currently only a smaller share of total capacity. 7nm was only around 50% utilization, compared to 110% a year ago. The recent chip shortage was mostly from 28nm or above. Think automotive, and the like. The inventory correction happening now is from a strong reduction in smartphone business, and HPC is also down thanks to PC sales declining 10-15% this year. And there is nothing surprising about this, TSMC has been guiding this inventory correction for more than a year now.

- addaon 3y ago> The recent chip shortage was mostly from 28nm or above. As a reminder to others, 28 nm was the last planar process; there's a discontinuity in cost moving below 28 nm to FinFET processes. For applications which don't need the last bit of density of power efficiency, 28 nm is likely to stay a sweet spot for a long, long time to come.
- ls612 3y agoWith 3nm being the last of the FinFETS will it end up in a similar situation in a decade? Will it be used for a lot of applications like 28nm is now for a long time?
- addaon 3y agoIt comes down to what the cost delta ends up being between FinFETs and GAAFETs, and if that's where the discontinuity is. I suspect that, even though EUV is "solved" now, the solutions are so expensive and sketchy that the DUV/EUV break is more likely to be important, with the final DUV processes being very long-lived. Unclear where this will end up exactly; I'd expect to see mature 7 nm DUV processes, but it's possible that the economics will either favor maturation of DUV + one or two EUV layers, or that a pure DUV 10 nm process with less multi-patterning ends up maturing so much cheaper that that wins out.
- trynumber9 3y agoApple buying every N3B wafer isn't enough to match the orders they placed. They had originally anticipated other customers on N3B too. But only Apple has an N3B design ready for manufacture. Intel - the only other major N3B customer - plans to use it for Arrow Lake S which is a late 2024 product. Every other major customer decided to wait for N3E because N3B is too expensive. TSMC therefore wants to push out the acquisition of additional machines until next year when N3E is ready. It's also the reason TSMC pulled in N3E a quarter or two.
- xster 3y agoThe article just obfuscates the news and hides a key detail at the end. China is a huge market for everything TSMC makes. China just showed this month that they can manufacture a near current generation flagship SoC using 90%+ domestic supply chains. This makes a big revision on future outlooks in China and ripples through demand forecast and capacity planning.
- mrtksn 3y ago>China just showed this month that they can manufacture a near current generation flagship SoC using 90%+ domestic supply chains I missed the news, any links on the subject?
- sbrother 3y agoDoes this mean that China is buying a bunch of ASML EUV machines?
- karmicthreat 3y agoChina won't be able to unless they develop the tech domestically.
- sbrother 3y agoRight that's what I thought, so how are they building a "near current generation flagship SoC"?
- tester756 3y ago>In the middle of a revolution in AI? Something doesn't add up here. Middle? hasn't the hype died already?
- oneTbrain23 3y agoRecession kicks in. Huawei able to do 7nm...but the bulk of chip sales are at 14nm+. China in 2022 end has successfully dominated that market near 80%. The pre-order for Huawei mate 60 already reaching 10m+ just a week ago and projected to reach 60m by 2024 end. Meanwhile China pretty much banned iPhone "subtlely" by forbiding their government servants using that (which can translate to around 100m people if you read between the line meaning ccp members). The euphoric news sensations are mostly CIA Uncle Sam propaganda. If you go into labor market or ask any HR the picture aren't as rosy as what you read on the media. Also, I have very reliable source China already at 3nm just yield is very low for mass market production. They should be able to reach that around Dec 2024 though TSMC probably will announce their 2nm. So 2025 is when China on par with TSMC making the war inevitable around 2026 as many fengshui masters calculated large chaotic event in that year.
- hunters_laptop 3y agoLOL you get voted down because mentioning those 3 words of american 'security organisations'
- halJordan 3y agoI know you've already been clobbered with responses, but i would like to point out how shit Ars has gotten to have messed you up like this. The enshittification of Ars is the thing that "doesnt add up for you."
- lisper 3y agoIt was Reuters, not Ars, but your point is well taken nonetheless.
- lubesGordi 3y ago" two sources familiar with the matter said." I don't really get how an article can be built off that. Isn't that completely insubstantial on the face of it? Are we supposed to just trust that some reuters journalist is sourcing this info from a credible primary source?
- baq 3y agothat's usually what journalists do. if you're concerned about Reuters credibility (you should be, for unrelated reasons), check this particular journalist's history.
- hef19898 3y agoToo lazy to look it up, but what exactly is it about said journalist? Good, bad? Because Reuters is one of the best journalistic sources out there. Edit: Two sources confirming stuff is not just how journalism works, but also intelligence services.
- porb121 3y agoyes, that is how journalism works.
- RevEng 3y agoThis would all be information that would be under NDA and certainly not to be discussed publicly. Industry insiders leaking information under condition of anonymity is the only reason we have any idea about what goes on behind the carefully curated PR from major corporations. Reputable journalists will confirm with multiple sources and only trust reputable sources. If you don't trust the publisher or journalist, check their previous releases to see how accurate their sources tend to be.

- blackoil 3y agoAny info if SAIC 7nm is having any impact? Or is it not feasible for non Huawei?
- throwaway4good 3y agoLatest rumor is expected sales of around 20m units - should cut into the iPhone 15 sales in China.
- throwaway4good 3y agoIt makes sense - lower sales from the iPhone 15 than expected - recession in lots of places, increased competition from China.
- spacedcowboy 3y agoThe iPhone 15 hasn't been released yet. Having expectations of high sales at this point might be premature...
- throwaway4good 3y agoThat new equipment is mostly for making iPhones.
- 1-6 3y agoSounds like market manipulation
- tmaly 3y agoI can't speak for the mobile phone market, but computer makers tend to be very cyclical based on the business cycle. I think we are likely seeing this to some degree.
- sevensor 3y agoI worked in semiconductor manufacturing, and I've been exposed to a lot of other industries. It's extremely volatile. Not quite like oil and gas production, but still enough to make your head spin.
- cvccvroomvroom 3y agoThe costs of building and idling Phoenix, AZ sites must be nontrivial. Without booked orders, buildout would be a waste of money.
- hunters_laptop 3y agoif you read a lot of chinese news, they said 2 biggest reasons: 1. many high skill engineers out from tsmc, moved to huawei and simc. 2. tsmc fear iphone 15 sales are falling especially in china
