What type of equipment TSME use in 2018 for N7? For ASML it was 1980i, what about other equipment?

You need to do the hard and dirty work to do that. I don't think EU elites are capable of planning a 15 year long industrial Policy plan to take back control of their cyber domain. Let alone execute it.

Differently from US and China, Europe lacks geopolitical sovereignty. Not because of our choice, but because of our history. And to invest to create an independent semiconductor industry (not to just subsidize an Intel fab in Germany), an industry able to compete at world level, you will necessarily step on the toes of someone that Bruxelles politicians don't go against, someone who allows them to remain there....and no, this someone is not the European citizens.

btw, I did a rough calculation on how many wafers per year is needed by Huawei from SMIC N+2 process

Again, I don't think SMIC produces this much right now, so would be hard pressed for a year or so until whenever domestic suppliers catch up and can help with things.

170k/year -> 14.k/month

Of course, it's quite possible that Huawei has been stocking up for a year or two of SMIC N+2 production already

This very much will depend on external conditions, for instance, the 2000 wafers on Ascend are way more strategical than the almost 30K on tablets...if US will fully ban Nvidia, we can expect those numbers will change a lot, moving on strategic targets and away from pure commercial/consumer stuff.

The fact that for Ascend you calculated just 2000 w/yr are enough is a big life insurance against possible US sanctions on AI chips....those 2K can quickly became 20K, rendering moot any possible US sanction on AI.

Copium. Many analysts are stilling being dismissive. Another thing is most of them have no idea if it is SMIC or Huawei's licensed SMIC's tech and equipment.

Huawei's new chip breakthrough likely to trigger closer US scrutiny -analysts​

SHENZHEN, China/SAN FRANCISCO, California (Reuters) - Huawei Technologies' breakthrough in making an advanced chip underscores China's determination and capacity for fighting back against U.S. sanctions, but the efforts are likely very costly and could prompt Washington to tighten curbs, analysts said.

Huawei unexpectedly unveiled the latest Mate 60 Pro smartphone last week during U.S. Commerce Secretary Gina Raimondo's visit in China, as the government readies a new $40-billion investment fund to bolster its developing chip sector.

The Mate 60 Pro is powered by its proprietary chip Kirin 9000s and manufactured by the country's top contract chipmaker SMIC using an advanced 7 nanometre (nm) technology, according to a teardown by Ottawa-headquartered TechInsights.

Its findings and claims by early users about the phone's powerful performance indicate China is making some headway into developing high-end chips, even as Washington has over the recent years ramped up sanctions to cut its access to advanced chipmaking tools.

It "demonstrates the technical progress China’s semiconductor industry has been able to make without EUV tools. The difficulty of this achievement also shows the resilience of the country’s chip technological ability," TechInsights analyst Dan Hutcheson said.

EUV refers to extreme ultraviolet lithography and is used to make 7 nm or more advanced chips.

"At the same time, it is a great geopolitical challenge to the countries who have sought to restrict its access to critical manufacturing technologies. The result may likely be even greater restrictions than what exist today."

Jefferies analysts said TechInsights' findings could trigger a probe from the U.S. Commerce Department's Bureau of Industry and Security, create more debate in the U.S. about the effectiveness of sanctions and prompt the Congress to include even harsher tech sanctions in a competition bill it is preparing against China.

"Overall the US-China tech war is likely to escalate," they said in a note.


A U.S. Department of Commerce representative did not immediately reply to a request for comment on Tuesday morning.

Huawei declined to comment. SMIC and China's State Council, which handles press queries on behalf of the Chinese government, did not immediately respond to requests for comments.

The most advanced chip SMIC had previously been known for making was 14nm, as it was barred by Washington in late 2020 from obtaining an EUV machine from Dutch firm ASML.

But TechInsights last year said it believed SMIC had managed to produce 7 nm chips by tweaking simpler DUV machines it could still purchase freely from ASML.

Some analysts including Jefferies' said there was also a possibility Huawei had purchased the tech and equipment from SMIC to make the chip rather than doing it in collaboration.

Whoever is making the chip, Tilly Zhang, an analyst at Gavekal Dragonomics, downplayed the success, citing a low yield rate which reduces the number of useable chips from each wafer and raises costs, and new export controls imposed by the Netherlands that will limit SMIC's access to more immersion DUV machine.

"They have just demonstrated that they are willing to accept much higher costs than are normally considered worthwhile ... It is only the combination of Huawei’s own large financial resources and generous government subsidies that could allow it to sell phones using these chips at normal market prices," Zhang said.


Reuters reported on Tuesday that China is set to launch a new state-backed investment fund that aims to raise about $40 billion for its chip sector, as the country ramps up efforts to catch up with the U.S. and other rivals.

Some research firms forecast SMIC's 7 nm process has an yield rate below 50%, versus the industry norm of 90% or more, and it would limit shipments to around 2-4 million chips, not enough for Huawei to regain its former smartphone market dominance.

Jefferies analysts reckon Huawei is preparing to ship ten million units of the Mate 60 Pro, though it may struggle to support that quantity with China-made 7 nm chips.

In that case it could turn to 10 nm chips, but with an estimated 20% yield, which refers to the number of working chips on each silicon wafer, Jefferies said, it would be far below the 90% for most consumer devices.

"The (U.S.) controls are imposing high costs for producing controlled technologies in China," said Doug Fuller, a chip researcher at the Copenhagen Business School, adding that the Chinese government was likely footing the bill.
They don't understand how the cost structure works. Even if the SoC costs 5x higher (from $30 to $150) the price of the phone goes up only 30% (from $370 to $490) because the SoC is nowhere near the most expensive part of the phone.

The display and mechanical enclosure are the actual high cost parts of the phone.

My point was to demonstrate that you don't need many wafers for AI chips.

Even with a full Nvidia ban. You can fill that with just 2k more wafers.

Question is juggling smartphone demand vs tablet vs desktops.

this guy is saying EUV prototype has rolled out. he is regarded as a pretty credible source
Well, we have been noticing here that many patents have come out, so system integration & prototype is next. I don't think it really matters whether prototype gets handed over this year or next. Bigger question is how smic gets involved from here.

With no euv alternative as @latenlazy said, do they have an experimental lab testing out true 5nm process with a barely tested euv by 2025?

Oh yes you do need tons of wafers for that. Nvidia already sold millions of AI chips this year,and there is still a huge back order.

LLM training need enormous amount of chips,and that demand will grow exponentially every year. There will always be shortage of high performance AI chips

Quantity sold globally doesn't equal wafers needed locally. It's about wafer efficiency and how many chips you get per wafer by local fabs, not just total global demand.

Remember, it's not solely about sheer volume but efficiency. If just 2K wafers/year suffice for Ascend, imagine the potential with 20K. This resilience makes U.S. sanctions on AI chips less consequential.

We know how many a800 they ordered this year. 100k.

Divide that by 50 per wafer and you get 2k wafers.

That's what a full replacement of Nvidia AI chips look like.
