文章原始标题:The latest news is that China's 7nm chips are manufactured using synchrotron radiation, which has 40 times the capacity of EUV lithography.

This large research facility was originally designed for scientific research in the extreme ultraviolet band.


Bengal71 -> MH.Yang
Can you please provide some source of this news?


Menthol -> MH.Yang
So, it uses a different method.
No wonder Huawei dares enough to release his own chip.
I thought it used DUV tricks.


White and Green with M/S -> MH.Yang
What is the source dude???


Skull and Bones
That is a big innovation.


Due to the global division of labour, if photolithography is too large to be transported from Europe to Asia, so the semiconductor industry is now using ASML's compact lithography technology.
The SSMB-EUV light source used in China has an output power of >100000KW, a capacity 40 times that of ASML, an accelerator length of >200 metres and a width of >20 metres alone, and it is capable of using dozens of EUVs at the same time with a beam splitter. The whole SSMB-EUV light source volume is equivalent to a photolithography factory. The construction of SSMB-EUV light source requires a complete industrial chain and huge capital investment, and China is the only country that can meet all the conditions.

由于全球分工,如果光刻机体积太大,就无法从欧洲运到亚洲,因此半导体行业现在使用的是 ASML 的紧凑型光刻技术。

Source of this news ? What is the unit cost of chips manufactured using this technique?


ziaulislam -> TriptiD
Cost...it's weird when talk about cost when it comes to China manufacturing thing
The question has been asked since 1990s and we deep down have always known the answer
Sooner or later China will get it done like it has always been the case


TriptiD -> ziaulislam
We are not talking about t-shirts and towels here.
The reason that I am asking about costs is that the chips could have been made using new tech in an experimental setting- which could be prohibitively expensive in a commerical setting. For example, you can "manufacture " gold in a particle accelerator, but the cost is prohibitive.


ziaulislam -> TriptiD
No we are talking about solar panels and other electronics costs
Ultimately China will figure out how to decrease the cost
They always do


epebble -> TriptiD
That question is easy to answer. If they sell only 100,000 7nm chips, your suspicion may be correct. But if they sell 100 million 7nm chips, they could not be making it at a loss and survive. In 2022, 1,400 million smartphones were sold. So, 100 million is only 7% of smartphones market.

这个问题很容易回答。如果他们只卖出10万片7纳米芯片,你的怀疑可能是正确的。但如果他们卖出了1亿个7纳米芯片,他们就不可能在亏损的情况下生存下来。2022 年,智能手机的销量为14亿部。所以,1亿只占智能手机市场的7%。

TriptiD -> epebble
Or they could just be using the existing process using ASML machines obtained by busting sanctions and not the technology the OP is claiming. That is why I asked him for the source of the news.

或者,他们可能只是通过打破制裁,使用获得的 ASML 机器的现有工艺,而不是题主所声称的技术。这就是我问他消息来源的原因。

epebble -> TriptiD
Unlikely. Even if they obtain them clandestinely, which is very difficult, as they are huge and enormously expensive and hence easily tracked. It is like surreptitiously buying a 747 or an aircraft carrier, they need huge amount of handholding services from the manufacturer. Imagine a large jet, times 1000. Can you steal this?
The $150 Million Machine Keeping Moore’s Law Alive

不太可能。即使他们秘密获得这些设备,也是非常困难的,因为这些武器体积庞大,价格昂贵,因此很容易被追踪到。这就好比偷偷购买一架 747 或一艘航空母舰,它们需要制造商提供大量的协助服务。想象一下,一架大型喷气式飞机,乘以 1000。你能偷到这个吗?

TriptiD -> epebble
You are forgetting even nations like Pakistan and North Korea have stolen missile and nuclear tech. So, yes, if China is motivated enough , they can definitely get an ASML machine by busting sanctions.

你忘了,就连巴基斯坦和朝鲜这样的国家也曾窃取导弹和核技术。所以,是的,如果中国有足够的动力,他们完全可以通过打破制裁获得 ASML 设备。

GreatHanWarrior -> TriptiD
Usually. Indians are better at these things. And they are proud of it.


epebble -> TriptiD
Missile and nuclear tech are easier than 7 nm. Neither Pakistan nor NK have high tech. Their roads, railroads and ports -19th Century technology - are built/supplied by China. Their challenge is to run a power grid.


TriptiD -> epebble
The question was about STEALING, not about whether it is high tech or low tech. If I have enough money and not located in China, I can purchase a ASML machine, but I can't purchase missile or nuclear tech.
And if China has indigenously developed an alternate tech, why is it keeping so quiet about it ? Doesn't it want to boast to the world that it defeated US sanctions and get customers for its indigenous technology?


BT -> TriptiD
None of these are true. Don’t water down China’s achievements in indigenizing semiconductor supply chain with fantasies.


FS -> BT
It’s more BS from the US intelligence. They think that if they make ridiculous statements then no one will believe that China can make 7nm chips.
What the US government and bureaucrats don’t seem to understand is that no amount of BS and hot air can change what is really happening.
It doesn’t matter whether the Western population thinks that China can make 7nm chips or not. China is going to keep making them and build fabs to make them.
For some strange reason, they have replaced reality with propaganda and think that this will do something.
I’m still at a loss as to what they think will happen. No amount of propaganda helped the Nazis when they lost in WWII.
I read an article that the Germans were shocked when allied troops showed up outside Berlin and started hammering the city.
They thought they were winning WWII!


etylo -> TriptiD
Chinese are not boastful like you Indians, don't think every one is like you.


GreatHanWarrior -> TriptiD
So. Please prove that the Chinese 7nm chip uses ASML EUV.
Please prove. Thank you.

那么请证明中国的7纳米芯片使用的是 ASML 的EUV光刻机。

beijingwalker -> TriptiD
Funny words from someone whose media produces the most lies in the world.
India has more fake news than any other country in the world
Nearly 60% of Indians had seen fake news against the global average of 57%, said a recent survey. Overall, India ranked seventh in Microsoft’s ‘Digital Civility’

最近的一项调查显示,近 60% 的印度人看到过假新闻,而全球平均比例为 57%。总体而言,印度在微软的“数字文明”中排名第七。

TriptiD -> beijingwalker
I have said so many times that I can't prove it because I don't even know if its true.
I am sure Tsinghua is doing some cutting edge research in the field. I doubt that the tech used in the SMIC chips in the Huawei chips is fully Chinese, but if someone presents evidence to that effect, then I will admit my doubts were ill-founded.
My understanding is that until now the known processes for making those chips required ASML machines. I am not saying China has not developed an alternative, only that there is no public records or evidence about what that process is.

我的理解是,到目前为止,制造这些芯片的已知工艺需要 ASML 的设备。我并不是说中国没有开发出替代方案,只是没有关于这一过程的公开的记录或证据。

Menthol -> TriptiD
That is the news.
Because Huawei is able to produce 7nm chips without ASML.
And now everyone is investigating and proposing several theories about it.
Up to now, no one really knows the truth.
My theory is probably a DUV trick, as SMIC launched 7nm processor for bitcoin mining using a DUV trick last year.
And it's not a coincidence because Huawei is launching 7nm processor instead of 5nm or 3nm.

因为华为能够在没有 ASML 的情况下生产7纳米芯片。
我的推测可能是某种 DUV 技巧,因为中芯国际去年推出的用于比特币挖矿的7纳米处理器就使用了一种DUV技巧。

GreatHanWarrior -> TriptiD
If India wants to look different from Pakistan. India develops its own technology first!
Currently, even cameras. India still relies on Chinese technology. India and Pakistan are not too different.


GreatHanWarrior -> TriptiD
Let me talk about a common sense topic - if Huawei chips use ASML. Americans will know Mate 60 before Chinese people.
The fact is. The ASML owned by China cannot manufacture 7nm chips.
Huawei 7nm chip is completely based on Chinese semiconductor technology!

让我来说一个常识性的话题——如果华为芯片使用的是ASML设备。美国人会比中国人更早知道Mate 60的。

The news comes from a product launch on 12 September 2023 reported by Huawei. Huawei mentions that they work with the Beijing Synchrotron Radiation Facility, BSF, on chips. Then the Chinese media enquired about its two factories in Xiongan and Shanghai, owned by CGST and Zhangjiang Hi-Tech, that can manufacture 7nm chips via synchrotron radiation.
The Beijing Synchrotron Radiation Facility, BSF, and Tsinghua University have collaborated to propose the SSMB-EUV light source solution (Steady State Microbeam), which overturns the concept of traditional lithography technology by no longer relying on shrinking the light source to improve the quality of the image, but rather, by enlarging and elongating the light source, to achieve the automatic adjustment of the different wavelengths of light, so as to achieve a higher degree of precision.
Of course, all the news now comes from the unofficial media splicing bits and pieces together and making guesses. It has not been confirmed by official organisations such as Huawei or Tsinghua University. I can understand if people don't believe it.
Satellite view of SSMB-EUV light source factory:
In June 2021, the official Chinese government media reported on the completion of the construction of the SSMB-EUV light source factory:
In February 2023, a press release from Tsinghua University's official media stated that the university's SSMB-EUV light source solution and technology had been put to practical use after spending 10 years and had solved a problem that was a major national need in the field of photolithography:

这一消息来自华为公司于2023年9月12日的产品发布会。华为提到,他们与北京同步辐射中心(BSF)合作开发芯片。随后,中国媒体询问了CGST 和张江高科在雄安和上海的两家工厂,这两家工厂可以通过同步辐射生产7纳米芯片。
北京同步辐射中心(BSF)与清华大学合作,提出了 SSMB-EUV 光源方案(稳态微聚束),颠覆了传统光刻技术的概念,不再依靠缩小光源来提高成像质量,而是通过放大和拉长光源,实现不同波长光的自动调节,从而达到更高的精度。
SSMB-EUV 光源工厂卫星图:

2021 年 6 月,中国官方媒体报道了 SSMB-EUV 光源工厂竣工的消息:

2023 年 2 月,清华大学官方媒体发布新闻稿称,该校的 SSMB-EUV 光源方案和技术历经 10 年时间终于投入实际应用,解决了光刻领域的国家重大需求问题:

Menthol -> MH.Yang
I think this project is not related to the current Huawei 7nm chips.
I think this project is aiming for 1nm chips in the future.
There are still several years away for the launching of 1nm chips, there are still a lot of time for China.
I also wonder, what is China progress on the carbon or graphene based chip?


FuturePAF -> Menthol
Or some kind of glass based chips?
Intel seems pretty excited about glass substrates
Intel has announced a a glass substrate breakthrough, which will make its future chips faster and more efficient.


TriptiD -> MH.Yang
Thanks for posting this. I have met a lot of really smart Tshingua graduates, so I have great respect for this university. However, the leap from research in a university and commerical production is a big one and your posts don't provide enough authoritative information to demonstrate this has been done. My main concern is what the unit cost of production will be, taking into account capital costs. The chips in the new phone carry the SMIC label. How is SMIC involved in the process you have described ?


MH.Yang -> TriptiD
The two plants belong to CGST and Zhangjiang Hi-Tech, two companies under the Beijing Synchrotron Radiation Facility, BSF.
Huawei announced and thanked Beijing Synchrotron Radiation Facility, BSF for their cooperation on the chips at the conference.
Tsinghua University submitted and announced the theory and proposal of SSMB-EUV 10 years ago, and Tsinghua University announced the successful construction of SSMB-EUV factory in February this year.
In February this year, the Chinese government media announced that Beijing Synchrotron Radiation Facility, BSF had built two factories using Tsinghua University's technology and proposal.
Do you see the connection and logic between these events?

这两家工厂属于 CGST 和张江高科,它们是北京同步辐射设施(BSF)下属的两家公司。
10 年前,清华大学提交并公布了 SSMB-EUV 的理论和方案,今年 2 月,清华大学宣布 SSMB-EUV 工厂建设成功。
今年 2 月,中国政府媒体宣布,北京同步辐射设施(BSF)已利用清华大学的技术和方案建造了两座工厂。

TriptiD -> MH.Yang
Well, there is some connection but still lot of unanswered questions. How is SMIC involved in all this ? It is their name on the chip, after all. Which entity owns the IP ? Have relevant patents been filed in China ? By whom? And what about the US and other Western countries ? Wouldn't whichever Chinese entity made the breakthrough? Then why hasn't anyone in the West spotted these patent applications yet ?


GreatHanWarrior -> TriptiD
Sorry. I don't know what you're being stubborn about.
A new Huawei chip packaging patent reveals performance verification technology
China’s patent office recently published a new Huawei chip packaging technology patent with application number CN116547791A. The title is “a chip package and a Method for preparing chip package”. It was applied on December 16, 2020, and approved on August 4th, 2023.
If India wants to look different from Pakistan. Firstly, India should address the illiteracy issues

中国专利局最近公布了一项新的华为芯片封装技术专利,申请号为 CN116547791A。专利名称为“一种芯片封装和制备芯片封装的方法”。该专利于 2020 年 12 月 16 日提出申请,并于 2023 年 8 月 4 日获得批准。如果印度想与巴基斯坦有所不同。印度应该先解决文盲问题。

TriptiD -> GreatHanWarrior
This is a Chinese patent that was applied for in 2020. Huawei probably has hundreds if not thousands of chip-related patents . Are you saying the one you have posted this patents the process that was used to make the SMIC chips on the new Huawei phone ? So, Huawei has had the process since before 2020 ? Why is SMIC's name on the chip if the IP belongs to Huawei?

这是 2020 年申请的一项中国专利。华为可能拥有成百上千项与芯片相关的专利。你是说,你贴出的这项专利就是用于制造华为新手机上中芯国际芯片的工艺吗?那么,华为在 2020 年之前就已经拥有了这一工艺?如果知识产权属于华为,为什么芯片上会有中芯国际的名字?

GreatHanWarrior -> TriptiD
What are you being stubborn about?
Huawei patents EUV lithography tools used to make
Huawei has patented one component used in EUV lithography systems that is required to make high-end processors on sub-10 nm nodes. It solves the problem of interference patterns created by the ultraviolet light that would otherwise make the wafer uneven.

华为已为用于超紫外光刻系统的一个组件申请了专利,该组件是在 10 纳米以下节点制造高端处理器所必需的。它解决了紫外光产生的干涉图案问题,否则紫外光会使晶片不平整。

GreatHanWarrior -> TriptiD
The fact is. The ASML owned by China cannot manufacture 7nm chips!
Can you understand?


GreatHanWarrior -> TriptiD
Huawei EUV Scanner Patent Suggests Sub-7nm Chips for China
Huawei has filed a patent application covering an extreme ultraviolet (EUV) lithography scanner, according to UDN. If the company builds such a scanner and achieves decent productivity, uptime, and yields, Chinese chipmakers could produce chips on sub-7nm-class technologies. The only question is when.
In mid-November, Huawei filed an application with the State Intellectual Property Office for a patent covering an EUV scanner and its key components. The patent application number is 202110524685X, reports MyDrivers.
The patent application appears to cover all crucial components of an EUV scanner, including a 13.5 nm EUV light generator (light source), a set of reflecting mirrors, the lithography system, and 'control management technologies' (we would speculate that this is how they call metrology), according to descrlptions published by various media sources.

《华为超紫外扫描仪专利表明中国将采用 7 纳米以下芯片》(链接)
据 UDN 报道,华为已提交了一份关于极紫外(EUV)光刻扫描仪的专利申请。如果该公司能制造出这样的扫描仪,并实现良好的生产率、正常运行时间和产量,那么中国的芯片制造商就能利用 7 纳米以下的技术生产芯片。唯一的问题是什么时候。
11 月中旬,华为向国家知识产权局提交了一份专利申请,内容涉及 EUV 扫描仪及其关键部件。据 MyDrivers 报道,专利申请号为 202110524685X。根据各种媒体发布的描述,该专利申请似乎涵盖了 EUV 扫描仪的所有关键部件,包括 13.5 纳米 EUV 光发生器(光源)、一组反射镜、光刻系统和“控制管理技术”(我们推测这是他们对计量的称呼)。

TriptiD -> GreatHanWarrior
Thanks for the link. No one doubts China is making progress on EUV but so far, until it becomes clear how the SMIC chips were produced, there is no evidence it has succeeded in doing so on an industrial scale.


MH.Yang -> TriptiD
You don't seem to be aware that SMIC is under the same sanctions as Huawei. SMIC breaking 7nm represents the same thing as Huawei breaking 7nm.

你似乎不知道中芯国际和华为一样受到制裁。中芯国际突破 7 纳米制程与华为突破 7 纳米制程是一回事。

TriptiD -> MH.Yang
They are both sanctioned but the list of sanctions on them is different. Unless you are saying that in China, the corporate structure and is just a sham and intellectual property of Huawei can be freely handed over to SMIC on the orders of the CCP, then the two entities are distinct and a Huawei product is not the same as a SMIC product.
Anyway, if you see a Reuters link I posted earlier, some analysts think that the 7nm chips were produced through DUV at very low yields. Western companies wouldn't do this because it is not economical but it seems Huawei had no other option and does not mind eating the loss.


GreatHanWarrior -> TriptiD
When Huawei humiliates you with technology. You can only talk about CCP.
Not surprisingly. What a desperate attempt.


Dalit -> GreatHanWarrior
These Indians are assholes.


kuge -> TriptiD
i think china has its own duv machine SSA800.

Think about it, when Huawei started selling Mate 70. How hopeless are you?

New Wenjie M7 model system is as smooth as Mate 60 Pro, says Huawei

Do you have any proof that the chips is the Huawei phone were made using Chinese machines instead of DUV/EUV machines that were imported earlier ?


GreatHanWarrior -> TriptiD
How many times do I need to say it?
The EUV/DUV sold by ASML to China cannot produce 7nm chips!!!
Only Huawei has the technology to produce chips without using ASML products!
Can you understand human language?
Baby. Let me tell you another news.

ASML出售给中国的EUV/DUV光刻机无法生产 7纳米芯片!

Dalit -> TriptiD
Why are you begging for proof? As if that is going to get Kashmir back.


GreatHanWarrior -> Dalit
India = joke.

印度 = 笑话。

kuge -> GreatHanWarrior
actually 7nm or even 5nm can be made with DUV with multiple patterning but costly.
it is just uncertain china fabbed them with domestic equip or not.

实际上,7 纳米甚至 5 纳米都可以通过 DUV 多重图案化技术实现,但成本高昂。

GreatHanWarrior -> kuge
It is Huawei's patented technology. It's not about using “Western technology at a high cost”.
The EUV Litography System was currently created exclusively by Dutch company ASML and filed a similar patent (US2016007434A1) in 2016 but has a different scope of patents. ASML is not allowed to sell the machine to China.
The difference between the two patents is that Huawei uses a rotating illumination device to reduce the number of bright or dark patterns in the same area. It seems that Huawei really wants to overcome the vacancy in the EUV Litography market.
As EUV discovery helped bring chips to 7nm and lower process nodes, Huawei patents could help China's Semiconductor Manufacturing International Corporation (SMIC) ultimately compete with TSMC and Samsung Foundry

EUV光刻系统目前由荷兰公司ASML独家研发,并于2016年申请了类似专利(US2016007434A1),但专利范围不同。ASML公司不被允许向中国销售该设备。这两项专利的不同之处在于,华为使用了旋转照明装置,以减少同一区域内明暗图案的数量。看来,华为真的想克服 EUV 光刻市场的空缺。
由于 EUV 的发现有助于将芯片带入7纳米和更精细的工艺节点,华为的专利可以帮助中国中芯国际最终与台积电和三星晶圆厂竞争。

TriptiD -> GreatHanWarrior
You are an idiot. I am putting you an ignore.
It is well documented that SMIC has produced the 7 nm chips using multiple rounds of patterning using DUV technology. TSMC used the same process before the advent or EUV, but the yield is very poor and the cost of the chip using this process could be 10x the cost using EUV.
The DUV machines being used by SMIC are most likely either from ASML or Nikon.

有充分的资料显示,中芯国际利用DUV技术通过多重图案化生产出了7纳米芯片。台积电在EUV出现之前也采用了同样的工艺,但产量很低,采用这种工艺的芯片成本可能是采用EUV工艺的 10 倍。

Han Patriot -> TriptiD
You need to chill bro. Nobody knows which process was used and nobody even knows it was a loss as you said. Nobody is stupid enough to make 40mil phones for a loss. If it is indeed SMIC, Mr. Liang the Chinese from Taiwan aka Taiwanese found a way to scale it up and improve the yield.
There is news coming out that SMIC Duvs can't satisfy 40mil chips and SSA800 is already running and producing. It's up to you to believe what you want but just because India can't make it doesn't mean they can't.


TriptiD -> Han Patriot
No one knows for sure because neither SMIC nor Huawei has spoken about it, but there is plenty of circumstantial evidence that DUV process with multiple patterning was used.


Han Patriot -> TriptiD
The point is you benchmark yourself to India. A few years ago nobody believed China could make advanced turbofans.


GreatHanWarrior -> TriptiD
You are a hopeless little idiot.
Return to a common sense question. If you use ASML/Nikon to produce chips, Americans won't know????
I have enough evidence. If you use ASML to produce 7nm chips. Americans will immediately remotely shut down all EUV/DUVs!


Menthol -> MH.Yang
I can't wait to see Huawei launching 5mn chip and so on.


Menthol -> MH.Yang
I think China technology advancement is no longer tied to the West. Instead of trailing behind or collaborating, China is able to take another path.
Since China research is already the world biggest, that explain everything.


BTW: According to experts in the field, if synchrotron radiation technology is used, it can achieve a 1NM effect with a 7NM stack, with the drawback of only a slightly higher heat generation.
Such a factory is something that only China is capable of building. Not only does it require a lot of industrial support and a lot of capital investment, it also has a lot of unique technologies and patents in the hands of Chinese state-owned enterprises. For example, 100,000 KW of power needs to be transmitted by ultra-high voltage, which is a unique technology and patent of China's power grid. The vast majority of countries, including the United States, do not have ultra-high voltage power grids, and China is the only country that has the ability to build such a plant.


Han Patriot -> MH.Yang
Theoretically it is possible since weakness is in shrinking the component size. They are compensating this by using another approach. Instead of killing a mosquito with a small tennis racquet, using a big racquet the size of a room.


MH.Yang -> Han Patriot
Some people know very well that the Chinese Government is very far-sighted and often engages in very long-term planning. But they still believe that Beijing was not ready to deal with the semiconductor issue until the United States launched sanctions.
Some know that China is the only country with a complete industrial chain, and that its industrial scale and research capabilities are much larger than those of the Netherlands. But they still believe that China will use the same methods as the Netherlands to manufacture semiconductors.


Menthol -> MH.Yang
Yes, based on my observation for years, China government is far sighted and do long term planning.
It's always went to the basic first, then stepping the ladder one by one.
Chinese government is also love to do social and economic experience, like setting up special zones with special social and economic policies. If it's successful, then it will be implemented national wide.


Han Patriot -> MH.Yang
This will buy time to miniturize the components further. Coupled with chiplet tech, Huawei has a big chance to win this race.


CIA Mole -> Han Patriot
China is 100% reactive and not proactive, unable to see anything coming from sanctions to covid to economy


Recent progress of SSMB EUV light source project at Tsinghua University

清华大学 SSMB 超紫外光源项目的最新进展(注:专业内容很长,需要的可以自行查看以上链接)

Menthol -> 艹艹艹
"In relatively low price"
Again, every time I read China research report, I see a lot the words of "low price".
It's truly helping humanity, improving everyone's standard of living.


Will it reduce cost for everything in future?
Any innovation is good Innovation.


MH.Yang -> mmr
Any area where China joins in will result in a price dafu drop.


This is highly exaggerated
In reality, one thought process is that China are MASTERS of upscale and NOVICES of micro scale
So a school of experts feel
Why should we spend all our money on micro scale engineering which was NEVER our expertise
Chinese cracked most of their tough problems by RISING THE SCALE
Now they say rather than to manufacture fine extreme light sources, they already can manufacture immensely powerful light sources on large scale
Likewise they can never make lenses like Zeiss because that's microscale, yet they can make large focal precision optics and be the best in the world at it
Now with such a huge scale, you cannot build EUV machines or mother machines but YOU CAN BUILD A FACTORY!!!


A Massive Factory that if it works could make Chipmaking the equivalent of an Industry Assembly Line which the Chinese are not just masters but super masters
So you will have factories that will resemble EUV machines churning out 1.6 Billion Chips every time
Of these 80% Chips will be Junk, 15% Chips will be low quality yet 5% Chips will be high yield and great quality
The experts claim that even this 5% which will be cost effective because of the large scale of the process
So far they kept trying to copy the West which are experts on micro scale and precision but suck at upscale today
They treated EUVs like an Engineering Problem and that's not their greatest strength
Now they treat EUVs like a Production problem and thats their greatest strength
Currently this is one of the three routes chosen by China to develop their own cutting edge semiconductors
The other routes include Innovative Stacking processes using DUVs and not needing EUVs at all
And a third route to make EUV’s conventionally
The Timeline is 2027–2030
It's not next year


We'll have to see if Huawei offers to sells this latest 7nm Kirin chip to other Chinese computer and smartphone makers. This chip is still 2 gen behind TSMC's latest 3nm nodes but of course barely much realistic difference between 7nm and 3nm when the alternative is either 14nm manufacturing or no chips at all.


Even though a solid source is not established here, with the track record of the Chinese I would choose to believe it. I anticipated it coming when the sanctions were applied. Chinese people always defeated sanctions in the past.
My next prediction is China will surpass ASML, TSMC, Samsung and other western tech companies in chip technology, perhaps in the next 3/4 years. What they will continue to lack is google services, they are not trying to develop google like services for global consumers which is a mistake.

我的下一个预测是,也许在未来3到4年内,中国将在芯片技术方面超过 ASML、台积电、三星和其他西方科技公司。他们将继续缺乏的是谷歌服务,他们没有尝试为全球消费者开发类似谷歌的服务,这是一个失误。

Menthol -> Bengal71
The original plan is use 7nm chip in 2022.
But because of USA sanctions, it was delayed up to the end of 2023.

原计划在 2022 年使用 7 纳米芯片。
但由于美国的制裁,被推迟到 2023 年底。

I saw this, no idea how much reliable information.
Microbunching illuminates new technological horizon-Tsinghua University www.tsinghua.edu.cn
A scheme that causes electrons to form microbunches’ could yield high power and coherent extreme-ultraviolet light, and perhaps the means to produce circuits faster.A new source of high-power extreme-ultraviolet (EUV) light, steady-state microbunching (SSMB), is peeking over the horizon, following a proof-of-principle experiment published in Nature. Corresponding author, Chuanxiang Tang, says the potential power of SSMB EUV could be used to etch more-intricate patterns onto semiconductor circuits.


Char -> StraightEdge
EUV lithography machines made in China do not need to be portable, and the technical requirements for lenses and photoresists will be reduced.


Menthol -> StraightEdge
I still don't know whatever Huawei 7nm chip is made using this technique or DUV.
But the news you posted is an idea to fabricate 1nm in the future, even below 1nm.


MH.Yang -> Menthol
Let me explain it this way. There are various sizes of light segments in a beam of light, 12nm, 7nm, 5nm and so on.
ASML's machines need to be transported to Asia, so they are small. ASML's machines are also relatively small in power due to the lack of extra high voltage power grids in countries other than China.
So ASML's machine is limited to intercepting only one size of light segment at a certain frequency segment. For example, a 7nm machine can only intercept a 7nm segment.
China's SSMB-EUV programme takes advantage of China's extra-high voltage grid to provide super-high input power, and it's essentially a lithography machine larger than an aircraft carrier.SSMB-EUV extends the distance of the intercepted light segments dramatically, and depending on the frequency, different sized segments are concentrated at different nodes. Then we can get different sizes of light segments at different nodes to make different sizes of chips. For example, make 24mm at point A, 12nm at point B and so on. This solution can drastically reduce the cost, improve the yield and increase the manufacturing speed.
