Huawei Prepares EUV Scanner for Sub-7 nm Chinese Chips
Huawei, the Chinese technology giant, has reportedly filed patents that it is developing extreme ultraviolet (EUV) scanners for use in the manufacturing process of semiconductors. This news comes amid increasing tensions between Huawei and the US government, which has imposed a series of sanctions on the company in recent years. According to UDN, Huawei has filed a patent that covers the entire EUV scanner with a 13.5 nm EUV light source, mirrors, lithography for printing circuits, and proper system control. While filing a patent is not the same as creating an accurate EUV scanner, it could enable China to produce a class of chips below 7 nm and have a homegrown semiconductor production, despite the ever-increasing US sanctions.
The development of EUV scanners is a significant milestone for Huawei and the semiconductor industry. However, the company's progress in this area may be hindered by the US government's sanctions, which have limited Huawei's access to certain technologies and markets. It is important to note that Chinese SMIC wanted to develop EUV fabrication based on third-party EUV tools; however, those plans were scrapped as the Wassenaar agreement came into action and prohibited the sales of advanced tools to Chinese companies. Huawei's development could represent a new milestone for the entire Chinese industry.

Ultimately if a company is dominating a market without using their leverage to prevent others from entering the market while driving innovation that's acceptable.
That said, markets with one dominating player should be subject to frequent review as there is a large chance for undesirable situations to develop under the surface. A company that is not abusing it's position should have no problem with this.
Even if ASML would provide a licensing structure to its EUV technologies, they would honestly just be giving their exisiting supply chain more pressure. The fact is, many of the stuff inside these machines simply isn't produced in the vast majority of the world, and is built on yet another stack of unique technologies.
I say, GL Huawei, you do you, I think the vast majority of this message is political. China is losing even its access to DUV scanners, and now they 'poof!' have an EUV design going? Its the ultimate middle finger at 'Murica, and nothing else. So: Good luck! We'll see those fantastic chips soon, won't we?
In other news, I heard China 'cured Omicron' by simply not calling it a problematic disease anymore. What was grounds for a lockdown a month or two ago, is now nothing but a cough and a sneeze. All is well here boys, you can move on now. We're talking about an autocratic regime here desperately trying to save face. Place that lens (! :D)) on the EUV development here and you really know what's what.

The reality though is that a few million will die here, after several years under stringent lockdown policies. Sounds comfy :)

They are the only one how can they be price fixing? i don't think you know what that means.
US pressure and sanctions?! What! That could be a barrier to cpu manufacturing, sure. But lithography?! Even if the Chinese got the machines how would that help them making new machines? having one to copy?!
:kookoo:
The big players had massive stocks of 28nm wafers years ago, TSMC sold this for cheap to Chinese companies undercutting SMIC. This industry is full of manipulation, and the chips wars have just heated up
The US did the samething to Japans semiconductor industry as well.
I think that monopoly observations about ASML are legitimate and accurate, they dictate the market. However they developed their technology in house and through decades of R&D.
I hope China makes breakthroughs that shake up the monopolistic market we have now. Nvidia and AMD being good reasons why. There are good reasons to have selfishly altruistic hopes for our species:
China or any country making breakthroughs with tech, innovative scientific research, or social justice progress benefit humanity and the free-market PH balance.
Canon is farther behind, this is their best:
global.canon/en/product/indtech/semicon/fpa6300es6a.html
But I noticed Canon has "i-line Steppers for Back-End-Of-the-Line (BEOL) and Advanced Packaging Applications" with a 52 x 68 mm exposure field. That's the size of interposers they should be able to make. So interposers aren't limited by the same 26 x 33 mm size as chips are. It was ASML's customers that helped create this monopoly. Intel, TSMC and Samsung all invested in it in 2012, when it needed money to develop EUV.
Fact is, 'we' own this market.
huawei is attempting to use a LED, it’s not going to work.
The complexity of getting high yield on ASML DUV systems at 10nm is why Intel had such a hard and long time getting there, but obviously it can be done, and done in volume with good yield.
And just to note, TSMC "N7" is actually a 10nm node. I'm going to refer to the 'real' 10nm, which includes N7, N6, and Intel 7. This is actually the crossover point where it seems DUV can't be stretched much more.
Unlike the ASML systems, where ASML went for EUV on sub 14nm nodes, Nikon's equipment appears to be specifically designed to use DUV and multiple patterning to achieve higher density.
Nikon's claim 275 wafers/hour using multiple patterning - which is just a few percent below ASMLs top end DUV equipment's max speed which is usually hovering just below 300 wafers/hr.
Intel used ASMLs DUV systems, since Nikon's equipment wasn't out until 2019 and Intel was already making its first gen 10nm chips at that time (Ice Lake). ASML had EUV systems out two years earlier (2017) that could do 10nm, vs Nikon in 2019.
That's not really much difference.
Mainly my point was that there are in fact other competitors in this space, ASML is not the only one, and not everyone has to use an approach identical to ASML to achieve similar results.
As far as competing with China in this space, the west dominates right now. I'd be a lot more concerned about where people are going to get a MOSFET or LCD display if for example, trade with China were to stop for whatever reason.
We'd probably wind up with a glut of 7nm chips, which are useless without all those other not so sexy parts like capacitors, resistors, diodes, power switching transistors, LCD displays and so on that we *don't* make in the west.
Here's an interesting picture of Shanghai, 1990 vs 2010 :
Lots of companies make cars. Only SSC (Shelby SuperCars) makes commercial road legal cars that go over 300mph.
In the world you might have 5-10 shops equipped with a $1,000,000 machine that services a critical component of this car.
5-10 chip companies order a $10,000,000+ production machine from the company that makes the best one.
It's not a consumer product. No one (except maybe China/Iran/Cuba/North Korea/Russia) wants to invest billions of dollars to engineer a new one, and then sell 3-5 of them.
It's not a monopoly when you have the best of something - this occurs in every industry.
Again I'd be a lot more worried about not so cutting edge stuff. The US and Europe have plenty of capability to make sub 10nm chips. China has nearly zero capability below 14nm right now, and despite some flag waving probably won't have 10nm for 3-5 more years. By then, the west will have moved on to 5nm. I mean the real 5nm, otherwise known as Intel 4/3 and TSMC N3, perhaps even 3nm otherwise known as Intel 18/20A and TSMC N2.
What we lack, is the ability to make LCD driver chips, MOSFETs, capacitors, transformers, and many other mundane parts.
That is why TI's expansion in Sherman TX is probably far more important than a new N5 fab in Arizona.

We didn't get stuck at 14nm by accident, it wasn't without effort that DUV and sub 14nm didn't get done with EUV as sub 14nm was expected to use.
It was because making EUV happen at all pushed the science of what's possible beyond what was possible that light source alone took years to develop.
And even ASML accept there is plenty of refinement still necessary to push it's use since pelicles are still an issue with earlier degradation then Ideal.
And it's important to note that in many cases those negative comments about China's government were earned, we are not stupid, but we are also fair and I would guess in all cases people are just as negative in public about their own government, I know I am.
No the edge of what's possible is often no where near the limit's of the laws of physics.
As I said creating the light source for the specific wavelength of light required which can output as required consistently and for a time span that isn't pointless.
The science of going beyond what's possible isn't the same as beyond the laws of physics.
What man or woman can possibly make is at the edge of what's possible in scientific and engineering terms.
ASML have had to push beyond that point continuously and consistently to be in the lead.
Plus new paradigm of engineering excellence had to be developed to create assemblies as accurate as required, including the many mirrors if you can still call them that.
No one said ASML makes new physics.
I didn't.
I said that they're pushing what's possible for humans to make.
And creating systems and devices that humans have not before been possible to make at all.
And some of these, like the light source took a degree of innovation, a lot of time and a significant amount of money to develop.
Should they f£#@, be forced to split and pass that effort to someone else to make money off.
I have no shares, I'm a consumer only yet I see no sense in that.
As a matter of fact, TSMC itself stated that N5 is not '5nm'.
If you aren't aware of this, you might want to strive to get better educated on these things. So N5 is just N5, it has nothing to do with 5nm.
